Imap

loObject = createobject("CkImap")

When set to .T., causes the currently running method to abort. Methods that always finish quickly (i.e.have no length file operations or network communications) are not affected. If no method is running, then this property is automatically reset to .F. when the next method is called. When the abort occurs, this property is reset to .F.. Both synchronous and asynchronous method calls can be aborted. (A synchronous method call could be aborted by setting this property from a separate thread.)

top

When .T. (the default) the Append method will mark the email appended to a mailbox as already seen. Otherwise an appended email will be initialized to have a status of unseen.

top

The UID of the last email appended to a mailbox via an Append* method. (Not all IMAP servers report back the UID of the email appended.)

top

Can be set to "XOAUTH2", "CRAM-MD5", "NTLM", "PLAIN", or "LOGIN" to select the authentication method. NTLM is the most secure, and is a synonym for "Windows Integrated Authentication". The default is "LOGIN" (or the empty string) which is simple plain-text username/password authentication. Not all IMAP servers support all authentication methods.

The XOAUTH2 method was added in version 9.5.0.44.

Note: If SPA (i.e. NTLM) authentication does not succeed, set the Global.DefaultNtlmVersion property equal to 1 and then retry.

top

Applies to the PLAIN authentication method. May be set to an authorization ID that is to be sent along with the Login and Password for authentication.

top

If set to .T., then all Fetch* methods will also automatically download attachments. If set to .F., then the Fetch* methods download the email without attachments. The default value is .T..

Note: Methods that download headers-only, such as FetchSingleHeader, ignore this property and never download attachments. Also, signed and/or encrypted emails will always be downloaded in full (with attachments) regardless of this property setting.

top

If .T., then the following will occur when a connection is made to an IMAP server:

1) If the Port property = 993, then sets StartTls = .F. and Ssl = .T.
2) If the Port property = 143, sets Ssl = .F.

The default value of this property is .T..

top

The IP address to use for computers with multiple network interfaces or IP addresses. For computers with a single network interface (i.e. most computers), this property should not be set. For multihoming computers, the default IP address is automatically used if this property is not set.

The IP address is a string such as in dotted notation using numbers, not domain names, such as "165.164.55.124".

top

Contains the IMAP server's domain name (or IP address) if currently connected. Otherwise returns an empty string.

top

Maximum number of seconds to wait when connecting to an IMAP server. The default value is 30 (units are in seconds).

top

If set to a file path, causes each Chilkat method or property call to automatically append it's LastErrorText to the specified log file. The information is appended such that if a hang or crash occurs, it is possible to see the context in which the problem occurred, as well as a history of all Chilkat calls up to the point of the problem. The VerboseLogging property can be set to provide more detailed information.

This property is typically used for debugging the rare cases where a Chilkat method call hangs or generates an exception that halts program execution (i.e. crashes). A hang or crash should generally never happen. The typical causes of a hang are:

1. a timeout related property was set to 0 to explicitly indicate that an infinite timeout is desired,
2. the hang is actually a hang within an event callback (i.e. it is a hang within the application code), or
3. there is an internal problem (bug) in the Chilkat code that causes the hang.

top

The Windows Domain to use for Windows Integrated Authentication (also known as NTLM). This may be empty.

top

A string containing an integer value that is the HIGHESTMODSEQ of the currently selected mailbox, or 0 if no mailbox is selected. (Chilkat decided to make this a string property for the chance that HIGHESTMODSEQ is an extremely large integer.)

Not all IMAP servers support HIGHESTMODSEQ. See RFC 4551 Section 3.1.1 HIGHESTMODSEQ Response Code for more information.

top

If an HTTP proxy requiring authentication is to be used, set this property to the HTTP proxy authentication method name. Valid choices are "Basic" or "NTLM".

top

The NTLM authentication domain (optional) if NTLM authentication is used.

top

If an HTTP proxy is to be used, set this property to the HTTP proxy hostname or IPv4 address (in dotted decimal notation).

top

If an HTTP proxy requiring authentication is to be used, set this property to the HTTP proxy password.

top

If an HTTP proxy is to be used, set this property to the HTTP proxy port number. (Two commonly used HTTP proxy ports are 8080 and 3128.)

top

If an HTTP proxy requiring authentication is to be used, set this property to the HTTP proxy login name.

top

Turns the in-memory session logging on or off. If on, the session log can be obtained via the SessionLog property. The default value is .F..

The SessionLog contains the raw commands sent to the IMAP server, and the raw responses received from the IMAP server.

top

The MIME source of the email last appended during a call to AppendMail, or AppendMime.

top

The last raw command sent to the IMAP server. (This information can be used for debugging if problems occur.)

top

Provides information in HTML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top

Provides information in plain-text format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top

Provides information in XML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top

The last intermediate response received from the IMAP server. (This information can be used for debugging if problems occur.)

top

Indicate whether the last method call succeeded or failed. A value of .T. indicates success, a value of .F. indicates failure. This property is automatically set for method calls. It is not modified by property accesses. The property is automatically set to indicate success for the following types of method calls:

• Any method that returns a string.
• Any method returning a Chilkat object, binary bytes, or a date/time.
• Any method returning a standard boolean status value where success = .T. and failure = .F..
• Any method returning an integer where failure is defined by a return value less than zero.

Note: Methods that do not fit the above requirements will always set this property equal to .T.. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

top

The raw data of the last response from the IMAP server. (Useful for debugging if problems occur.) This property is cleared whenever a command is sent to the IMAP server. If no response is received, then this property will remain empty. Otherwise, it will contain the last response received from the IMAP server.

top

The response code part of the last command response, if it exists. IMAP status responses MAY include an OPTIONAL "response code". A response code consists of data inside square brackets in the form of an atom, possibly followed by a space and arguments. The response code contains additional information or status codes for client software beyond the OK/NO/BAD condition, and are defined when there is a specific action that a client can take based upon the additional information. Examples of response codes are "NONEXISTENT" and "AUTHENTICATIONFAILED". The response code strings for a given failure condition may vary depending on the IMAP server implementation.

top

If logged into an IMAP server, the logged-in username.

top

After selecting a mailbox (by calling SelectMailbox), this property will be updated to reflect the total number of emails in the mailbox.

top

Set to true to prevent the mail flags (such as the "Seen" flag) from being set when email is retrieved. The default value of this property is false.

top

The IMAP port number. If using SSL, be sure to set this to the IMAP SSL port number, which is typically port 993. (If this is the case, make sure you also set the Ssl property = .T..

top

If .T., then use IPv6 over IPv4 when both are supported for a particular domain. The default value of this property is .F., which will choose IPv4 over IPv6.

top

The maximum amount of time (in seconds) that incoming data is allowed to stall while reading any kind of response from an IMAP server. This is the amount of time that needs to elapse while no additional response bytes are forthcoming. For the case of long responses, if the data stream halts for more than this amount, it will timeout. This property is not a maximum for the total response time, but only a maximum for the amount of time while no response arrives.

The default value is 30 seconds.

top

If .T., then the IMAP client will verify the server's SSL certificate. The certificate is expired, or if the cert's signature is invalid, the connection is not allowed. The default value of this property is .F..

top

The "CHARSET" to be used in searches issued by the Search method. The default value is "UTF-8". (If no 8bit chars are found in the search criteria passed to the Search method, then no CHARSET is needed and this property doesn't apply.) The SearchCharset property can be set to "AUTO" to get the pre-v9.4.0 behavior, which is to examine the 8bit chars found in the search criteria and select an appropriate multibyte charset.

In summary, it is unlikely that this property needs to be changed. It should only be modified if trouble arises with some IMAP servers when non-English chars are used in the search criteria.

top

The currently selected mailbox, or an empty string if none.

top

The buffer size to be used with the underlying TCP/IP socket for sending. The default value is 32767.

top

The separator character used by the IMAP server for the mailbox hierarchy. It is typically "/" or ".", but may vary depending on the IMAP server. The ListMailboxes method has the side-effect of setting this property to the correct value because the IMAP server's response when listing mailboxes includes information about the separator char.

Note: Starting in version 9.5.0.47, this property changed from a "char" type to a "string" type. The separator char property will always be a string of length 1 character.

top

Contains an in-memory log of the raw commands sent to the IMAP server, and the raw responses received from the IMAP server. The KeepSessionLog property must be set to .T. to enable session logging. Call ClearSessionLog to reset the log.

top

The SOCKS4/SOCKS5 hostname or IPv4 address (in dotted decimal notation). This property is only used if the SocksVersion property is set to 4 or 5).

top

The SOCKS5 password (if required). The SOCKS4 protocol does not include the use of a password, so this does not apply to SOCKS4.

top

The SOCKS4/SOCKS5 proxy port. The default value is 1080. This property only applies if a SOCKS proxy is used (if the SocksVersion property is set to 4 or 5).

top

The SOCKS4/SOCKS5 proxy username. This property is only used if the SocksVersion property is set to 4 or 5).

top

SocksVersion May be set to one of the following integer values:

0 - No SOCKS proxy is used. This is the default.
4 - Connect via a SOCKS4 proxy.
5 - Connect via a SOCKS5 proxy.

top

Sets the receive buffer size socket option. Normally, this property should be left unchanged. The default value is 4194304.

This property can be increased if download performance seems slow. It is recommended to be a multiple of 4096.

top

Sets the send buffer size socket option. Normally, this property should be left unchanged. The default value is 262144.

This property can be increased if upload performance seems slow. It is recommended to be a multiple of 4096. Testing with sizes such as 512K and 1MB is reasonable.

top

.T. if the IMAP connection should be TLS/SSL.

Note: The typical IMAP TLS/SSL port number is 993. If you set this property = .T., it is likely that you should also set the Port property = 993.

top

Provides a means for setting a list of ciphers that are allowed for SSL/TLS connections. The default (empty string) indicates that all implemented ciphers are possible. The TLS ciphers supported in Chilkat v9.5.0.55 and later are:

TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256
TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256
TLS_DHE_RSA_WITH_CHACHA20_POLY1305_SHA256
TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA
TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256
TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA
TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384
TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384
TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA
TLS_DHE_RSA_WITH_AES_256_CBC_SHA256
TLS_DHE_RSA_WITH_AES_256_GCM_SHA384
TLS_DHE_RSA_WITH_AES_256_CBC_SHA
TLS_RSA_WITH_AES_256_CBC_SHA256
TLS_RSA_WITH_AES_256_GCM_SHA384
TLS_RSA_WITH_AES_256_CBC_SHA
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA
TLS_DHE_RSA_WITH_AES_128_CBC_SHA256
TLS_DHE_RSA_WITH_AES_128_GCM_SHA256
TLS_DHE_RSA_WITH_AES_128_CBC_SHA
TLS_RSA_WITH_AES_128_CBC_SHA256
TLS_RSA_WITH_AES_128_GCM_SHA256
TLS_RSA_WITH_AES_128_CBC_SHA
TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA
TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA
TLS_RSA_WITH_3DES_EDE_CBC_SHA
TLS_ECDHE_RSA_WITH_RC4_128_SHA
TLS_RSA_WITH_RC4_128_SHA
TLS_RSA_WITH_RC4_128_MD5
TLS_DHE_RSA_WITH_DES_CBC_SHA
TLS_RSA_WITH_DES_CBC_SHA

To restrict SSL/TLS connections to one or more specific ciphers, set this property to a comma-separated list of ciphers such as "TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384, TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384". The order should be in terms of preference, with the preferred algorithms listed first. (Note that the client cannot specifically choose the algorithm is picked because it is the server that chooses. The client simply provides the server with a list from which to choose.)

The property can also disallow connections with servers having certificates with RSA keys less than a certain size. By default, server certificates having RSA keys of 512 bits or greater are allowed. Add the keyword "rsa1024" to disallow connections with servers having keys smaller than 1024 bits. Add the keyword "rsa2048" to disallow connections with servers having keys smaller than 2048 bits.

Note: Prior to Chilkat v9.5.0.55, it was not possible to explicitly list allowed cipher suites. The deprecated means for indicating allowed ciphers was both incomplete and unprecise. For example, the following keywords could be listed to allow matching ciphers: "aes256-cbc", "aes128-cbc", "3des-cbc", and "rc4". These keywords will still be recognized, but programs should be updated to explicitly list the allowed ciphers.

secure-renegotiation: Starting in Chilkat v9.5.0.55, the keyword "secure-renegotiation" may be added to require that all renegotions be done securely (as per RFC 5746).

best-practices: Starting in Chilkat v9.5.0.55, this property may be set to the single keyword "best-practices". This will allow ciphers based on the current best practices. As new versions of Chilkat are released, the best practices may change. Changes will be noted here. The current best practices are:

• If the server uses an RSA key, it must be 1024 bits or greater.
• All renegotations must be secure renegotiations.
• All ciphers using RC4, DES, or 3DES are disallowed.

Example: The following string would restrict to 2 specific cipher suites, require RSA keys to be 1024 bits or greater, and require secure renegotiations: "TLS_DHE_RSA_WITH_AES_256_CBC_SHA256, TLS_RSA_WITH_AES_256_CBC_SHA, rsa1024, secure-renegotiation"

top

Selects the secure protocol to be used for secure (SSL/TLS) connections. Possible values are:

default
TLS 1.3
TLS 1.2
TLS 1.1
TLS 1.0
SSL 3.0
TLS 1.3 or higher
TLS 1.2 or higher
TLS 1.1 or higher
TLS 1.0 or higher

The default value is "default" which will choose the, which allows for the protocol to be selected dynamically at runtime based on the requirements of the server. Choosing an exact protocol will cause the connection to fail unless that exact protocol is negotiated. It is better to choose "X or higher" than an exact protocol. The "default" is effectively "SSL 3.0 or higher".

top

Read-only property that returns .T. if the IMAP server's digital certificate was verified when connecting via SSL / TLS.

top

If .T., then the Connect method will (internallly) convert the connection to TLS/SSL via the STARTTLS IMAP command. This is called "explict SSL/TLS" because the client explicitly requests the connection be transformed into a TLS/SSL secure channel. The alternative is "implicit SSL/TLS" where the "Ssl" property is set to .T. and the IMAP client connects to the well-known TLS/SSL IMAP port of 993.

top

Contains the current or last negotiated TLS cipher suite. If no TLS connection has yet to be established, or if a connection as attempted and failed, then this will be empty. A sample cipher suite string looks like this: TLS_DHE_RSA_WITH_AES_256_CBC_SHA256.

top

Specifies a set of pins for Public Key Pinning for TLS connections. This property lists the expected SPKI fingerprints for the server certificates. If the server's certificate (sent during the TLS handshake) does not match any of the SPKI fingerprints, then the TLS handshake is aborted and the connection fails. The format of this string property is as follows:

hash_algorithm, encoding, SPKI_fingerprint_1, SPKI_fingerprint_2, ...

For example, the following string specifies a single sha256 base64-encoded SPKI fingerprint:

"sha256, base64, lKg1SIqyhPSK19tlPbjl8s02yChsVTDklQpkMCHvsTE="

This example specifies two SPKI fingerprints:

"sha256, base64, 4t37LpnGmrMEAG8HEz9yIrnvJV2euVRwCLb9EH5WZyI=, 68b0G5iqMvWVWvUCjMuhLEyekM5729PadtnU5tdXZKs="

Any of the following hash algorithms are allowed:.sha1, sha256, sha384, sha512, md2, md5, haval, ripemd128, ripemd160,ripemd256, or ripemd320.

The following encodings are allowed: base64, hex, and any of the encodings indicated in the link below.

top

Contains the current or last negotiated TLS protocol version. If no TLS connection has yet to be established, or if a connection as attempted and failed, then this will be empty. Possible values are "SSL 3.0", "TLS 1.0", "TLS 1.1", "TLS 1.2", and "TLS 1.3".

top

A positive integer value containing the UIDNEXT of the currently selected folder, or 0 if it's not available or no folder is selected.

top

An integer value containing the UIDVALIDITY of the currently selected mailbox, or 0 if no mailbox is selected.

A client can save the UidValidity value for a mailbox and then compare it with the UidValidity on a subsequent session. If the new value is larger, the IMAP server is not keeping UID's unchanged between sessions. Most IMAP servers maintain UID's between sessions.

top

This is a catch-all property to be used for uncommon needs. This property defaults to the empty string and should typically remain empty. Can be set to a list of the following comma separated keywords:

• "ProtectFromVpn" - Introduced in v9.5.0.80. On Android systems, will bypass any VPN that may be installed or active.
• "EnableTls13" - Introduced in v9.5.0.82. Causes TLS 1.3 to be offered in the ClientHello of the TLS protocol, allowing the server to select TLS 1.3 for the session. Future versions of Chilkat will enable TLS 1.3 by default. This option is only necessary in v9.5.0.82 if TLS 1.3 is desired.

top

If set to .T., then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is .F.. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

top

Version of the component/library, such as "9.5.0.94"

top

Adds a PFX file to the object's internal list of sources to be searched for certificates and private keys when decrypting. Multiple PFX files can be added by calling this method once for each. (On the Windows operating system, the registry-based certificate stores are also automatically searched, so it is commonly not required to explicitly add PFX sources.)

The pfxFilePath contains the bytes of a PFX file (also known as PKCS12 or .p12).

Returns .T. for success, .F. for failure.

top

Appends an email to an IMAP mailbox.

Returns .T. for success, .F. for failure.

Returns .F. on failure

top

Returns .T. if the underlying TCP socket is connected to the IMAP server.

Internally, this method makes a lower-level socket system call to check if the TCP socket is still connected.

top

Checks for new email that has arrived since the mailbox was selected (via the SelectMailbox or ExamineMailbox methods), or since the last call to CheckForNewEmail (whichever was most recent). This method works by closing and re-opening the currently selected mailbox, and then sending a "SEARCH" command for either RECENT emails, or emails having a UID greater than the UIDNEXT value. A message set object containing the UID's of the new emails is returned, and this may be passed to methods such as FetchBundle to download the new emails.

Returns .F. on failure

top

Creates an asynchronous task to call the CheckForNewEmail method with the arguments provided. (Async methods are available starting in Chilkat v9.5.0.52.)

Returns .F. on failure

top

Clears the contents of the SessionLog property.

top

Returns .T. for success, .F. for failure.

top

Creates an asynchronous task to call the CloseMailbox method with the arguments provided. (Async methods are available starting in Chilkat v9.5.0.52.)

Returns .F. on failure

top

Connects to an IMAP server, but does not login. The domainName is the domain name of the IMAP server. (May also use the IPv4 or IPv6 address in string format.)

Important: All TCP-based Internet communications, regardless of the protocol (such as HTTP, FTP, SSH, IMAP, POP3, SMTP, etc.), and regardless of SSL/TLS, begin with establishing a TCP connection to a remote host:port. External security-related infrastructure such as software firewalls (Windows Firewall), hardware firewalls, anti-virus, at either source or destination (or both) can block the connection. If the connection fails, make sure to check all potential external causes of blockage.

Returns .T. for success, .F. for failure.

top

Creates an asynchronous task to call the Copy method with the arguments provided. (Async methods are available starting in Chilkat v9.5.0.52.)

Returns .F. on failure

top

Same as the Copy method, except an entire set of emails is copied at once. The set of emails is specified in messageSet.

top

Creates an asynchronous task to call the CreateMailbox method with the arguments provided. (Async methods are available starting in Chilkat v9.5.0.52.)

Returns .F. on failure

Deletes an existing mailbox.

Note: The term "mailbox" and "folder" are synonymous. Whenever the word "mailbox" is used, it has the same meaning as "folder".

Returns .T. for success, .F. for failure.

top

Creates an asynchronous task to call the DeleteMailbox method with the arguments provided. (Async methods are available starting in Chilkat v9.5.0.52.)

Returns .F. on failure

top

Disconnects cleanly from the IMAP server. A non-success return from this method only indicates that the disconnect was not clean -- and this can typically be ignored.

Returns .T. for success, .F. for failure.

top

Creates an asynchronous task to call the Disconnect method with the arguments provided. (Async methods are available starting in Chilkat v9.5.0.52.)

Returns .F. on failure

top

Selects a mailbox such that only read-only transactions are allowed. This method would be called instead of SelectMailbox if the logged-on user has read-only permission.

Note: The term "mailbox" and "folder" are synonymous. Whenever the word "mailbox" is used, it has the same meaning as "folder".

Returns .T. for success, .F. for failure.

top

Creates an asynchronous task to call the ExpungeAndClose method with the arguments provided. (Async methods are available starting in Chilkat v9.5.0.52.)

Returns .F. on failure

top

Downloads one of an email's attachments and saves it to a file. If the emailObject already contains the full email (including the attachments), then no communication with the IMAP server is necessary because the attachment data is already contained within the emailObject. In this case, the attachment is simply extracted and saved to saveToPath. (As with all Chilkat methods, indexing begins at 0. The 1st attachment is at attachmentIndex 0.)

Additional Notes:

If the AutoDownloadAttachments property is set to .F., then emails downloaded via any of the Fetch* methods will not include attachments.

Note: "related" items are not considered attachments and are downloaded. These are images, style sheets, etc. that are embedded within the HTML body of an email.

Also: All signed and/or encrypted emails must be downloaded in full.

When an email is downloaded without attachments, the attachment information is included in header fields. The header fields have names beginning with "ckx-imap-". The attachment information can be obtained via the following methods:

imap.GetMailNumAttach
imap.GetMailAttachFilename
imap.GetMailAttachSize

Returns .T. for success, .F. for failure.

top

Creates an asynchronous task to call the FetchAttachment method with the arguments provided. (Async methods are available starting in Chilkat v9.5.0.52.)

Returns .F. on failure

top

Downloads one of an email's attachments and returns the attachment data in a BinData object. ***See the FetchAttachment method description for more information about fetching attachments.

Fetches the flags for an email. The bUid argument determines whether the msgId is a UID or sequence number.

Returns the SPACE separated list of flags set for the email, such as "\Flagged \Seen $label1".

If an empty string is returned, then it could be that the email referenced by msgId does not exist in the currently selected mailbox, or it simply has no flags that are set. To determine the difference, examine the contents of the LastResponse property. For the case where the message does not exist, the LastResponse will contain a "NO" and will look something like this:

aaah NO The specified message set is invalid.

For the case where the message exists, but no flags are set, the LastResponse will contain an "OK" in the last response line. For example:

...
aaah OK FETCH completed.

Downloads email for a range of sequence numbers. The 1st email in a mailbox is always at sequence number 1. The total number of emails in the currently selected mailbox is available in the NumMessages property. If the numMessages is too large, the method will still succeed, but will return a bundle of emails from startSeqNum to the last email in the mailbox.

Polls the connection to see if any real-time updates are available. The timeoutMs indicates how long to wait for incoming updates. This method does not send a command to the IMAP server, it simply checks the connection for already-arrived messages that the IMAP server sent. This method would only be called after IDLE has already been started via the IdleStart method.

If updates are available, they are returned in an XML string having the format as shown below. There is one child node for each notification. The possible notifcations are:

1. flags -- lists flags that have been set or unset for an email.
2. expunge -- provides the sequence number for an email that has been deleted.
3. exists -- reports the new number of messages in the currently selected mailbox.
4. recent -- reports the new number of messages with the /RECENT flag set.
5. raw -- reports an unanticipated response line that was not parsed by Chilkat. This should be reported to support@chilkatoft.com

A sample showing all possible notifications (except for "raw") is shown below.

<idle>
    <flags seqnum="59" uid="11876">
        <flag>\Deleted</flag>
        <flag>\Seen</flag>
    </flags>
    <flags seqnum="69" uid="11889">
        <flag>\Seen</flag>
    </flags>
    <expunge>58</expunge>
    <expunge>58</expunge>
    <expunge>67</expunge>
    <exists>115</exists>
    <recent>0</recent>
</idle>

If no updates have been received, the returned XML string has the following format, as shown below. The

<idle></idle>

NOTE:Once IdleStart has been called, this method can and should be called frequently to see if any updates have arrived. This is NOT the same as polling the IMAP server because it does not send any requests to the IMAP server. It simply checks to see if any messages (i.e. updates) from the IMAP server are available and waiting to be read.

Returns the last known "connected" state with the IMAP server. IsConnected does not send a message to the IMAP server to determine if it is still connected. The Noop method may be called to specifically send a no-operation message to determine actual connectivity.

The IsConnected method is useful for checking to see if the component is already in a known disconnected state.

top

Returns .T. if already logged into an IMAP server, otherwise returns .F..

top

Returns a subset of the complete list of mailboxes available on the IMAP server. This method has the side-effect of setting the SeparatorChar property to the correct character used by the IMAP server, which is typically "/" or ".".

Note: The term "mailbox" and "folder" are synonymous. Whenever the word "mailbox" is used, it has the same meaning as "folder".

The reference and wildcardedMailbox parameters are passed unaltered to the IMAP LIST command:

<font size="2" face="MS Sans Serif">
<b>FROM RFC 3501 (IMAP Protocol)</b>

      The LIST command returns a subset of names from the complete set
      of all names available to the client.  Zero or more untagged LIST
      replies are returned, containing the name attributes, hierarchy
      delimiter, and name; see the description of the LIST reply for
      more detail.

      An empty ("" string) reference name argument indicates that the
      mailbox name is interpreted as by SELECT.  The returned mailbox
      names MUST match the supplied mailbox name pattern.  A non-empty
      reference name argument is the name of a mailbox or a level of
      mailbox hierarchy, and indicates the context in which the mailbox
      name is interpreted.

      An empty ("" string) mailbox name argument is a special request to
      return the hierarchy delimiter and the root name of the name given
      in the reference.  The value returned as the root MAY be the empty
      string if the reference is non-rooted or is an empty string.  In
      all cases, a hierarchy delimiter (or NIL if there is no hierarchy)
      is returned.  This permits a client to get the hierarchy delimiter
      (or find out that the mailbox names are flat) even when no
      mailboxes by that name currently exist.

      The reference and mailbox name arguments are interpreted into a
      canonical form that represents an unambiguous left-to-right
      hierarchy.  The returned mailbox names will be in the interpreted
      form.

           Note: The interpretation of the reference argument is
           implementation-defined.  It depends upon whether the
           server implementation has a concept of the "current
           working directory" and leading "break out characters",
           which override the current working directory.

           For example, on a server which exports a UNIX or NT
           filesystem, the reference argument contains the current
           working directory, and the mailbox name argument would
           contain the name as interpreted in the current working
           directory.

           If a server implementation has no concept of break out
           characters, the canonical form is normally the reference
           name appended with the mailbox name.  Note that if the
           server implements the namespace convention (section
           5.1.2), "#" is a break out character and must be treated
           as such.

           If the reference argument is not a level of mailbox
           hierarchy (that is, it is a \NoInferiors name), and/or
           the reference argument does not end with the hierarchy
           delimiter, it is implementation-dependent how this is
           interpreted.  For example, a reference of "foo/bar" and
           mailbox name of "rag/baz" could be interpreted as
           "foo/bar/rag/baz", "foo/barrag/baz", or "foo/rag/baz".
           A client SHOULD NOT use such a reference argument except
           at the explicit request of the user.  A hierarchical
           browser MUST NOT make any assumptions about server
           interpretation of the reference unless the reference is
           a level of mailbox hierarchy AND ends with the hierarchy
           delimiter.

      Any part of the reference argument that is included in the
      interpreted form SHOULD prefix the interpreted form.  It SHOULD
      also be in the same form as the reference name argument.  This
      rule permits the client to determine if the returned mailbox name
      is in the context of the reference argument, or if something about
      the mailbox argument overrode the reference argument.  Without
      this rule, the client would have to have knowledge of the server's
      naming semantics including what characters are "breakouts" that
      override a naming context.

           For example, here are some examples of how references
           and mailbox names might be interpreted on a UNIX-based
           server:

               Reference     Mailbox Name  Interpretation
               ------------  ------------  --------------
               ~smith/Mail/  foo.*         ~smith/Mail/foo.*
               archive/      %             archive/%
               #news.        comp.mail.*   #news.comp.mail.*
               ~smith/Mail/  /usr/doc/foo  /usr/doc/foo
               archive/      ~fred/Mail/*  ~fred/Mail/*

           The first three examples demonstrate interpretations in
           the context of the reference argument.  Note that
           "~smith/Mail" SHOULD NOT be transformed into something
           like "/u2/users/smith/Mail", or it would be impossible
           for the client to determine that the interpretation was
           in the context of the reference.

      The character "*" is a wildcard, and matches zero or more
      characters at this position.  The character "%" is similar to "*",
      but it does not match a hierarchy delimiter.  If the "%" wildcard
      is the last character of a mailbox name argument, matching levels
      of hierarchy are also returned.  If these levels of hierarchy are
      not also selectable mailboxes, they are returned with the
      \Noselect mailbox name attribute (see the description of the LIST
      response for more details).

      Server implementations are permitted to "hide" otherwise
      accessible mailboxes from the wildcard characters, by preventing
      certain characters or names from matching a wildcard in certain
      situations.  For example, a UNIX-based server might restrict the
      interpretation of "*" so that an initial "/" character does not
      match.

      The special name INBOX is included in the output from LIST, if
      INBOX is supported by this server for this user and if the
      uppercase string "INBOX" matches the interpreted reference and
      mailbox name arguments with wildcards as described above.  The
      criteria for omitting INBOX is whether SELECT INBOX will return
      failure; it is not relevant whether the user's real INBOX resides
      on this or some other server.

Searches the already selected mailbox for messages that match criteria and returns a message set of all matching messages. If bUid is .T., then UIDs are returned in the message set, otherwise sequence numbers are returned.

Note: It seems that Microsoft IMAP servers, such as outlook.office365.com and imap-mail.outlook.com do not support anything other than 7bit us-ascii chars in the search criteria string, regardless of the SEARCH charset that might be specified.

The criteria is passed through to the low-level IMAP protocol unmodified, so the rules for the IMAP SEARCH command (RFC 3501) apply and are reproduced here:

<font size="2" face="MS Sans Serif">
<b>FROM RFC 3501 (IMAP Protocol)</b>

      The SEARCH command searches the mailbox for messages that match
      the given searching criteria.  Searching criteria consist of one
      or more search keys.  The untagged SEARCH response from the server
      contains a listing of message sequence numbers corresponding to
      those messages that match the searching criteria.

      When multiple keys are specified, the result is the intersection
      (AND function) of all the messages that match those keys.  For
      example, the criteria DELETED FROM "SMITH" SINCE 1-Feb-1994 refers
      to all deleted messages from Smith that were placed in the mailbox
      since February 1, 1994.  A search key can also be a parenthesized
      list of one or more search keys (e.g., for use with the OR and NOT
      keys).

      Server implementations MAY exclude [MIME-IMB] body parts with
      terminal content media types other than TEXT and MESSAGE from
      consideration in SEARCH matching.

      The OPTIONAL [CHARSET] specification consists of the word
      "CHARSET" followed by a registered [CHARSET].  It indicates the
      [CHARSET] of the strings that appear in the search criteria.
      [MIME-IMB] content transfer encodings, and [MIME-HDRS] strings in
      [RFC-2822]/[MIME-IMB] headers, MUST be decoded before comparing
      text in a [CHARSET] other than US-ASCII.  US-ASCII MUST be
      supported; other [CHARSET]s MAY be supported.

      If the server does not support the specified [CHARSET], it MUST
      return a tagged NO response (not a BAD).  This response SHOULD
      contain the BADCHARSET response code, which MAY list the
      [CHARSET]s supported by the server.

      In all search keys that use strings, a message matches the key if
      the string is a substring of the field.  The matching is
      case-insensitive.

      The defined search keys are as follows.  Refer to the Formal
      Syntax section for the precise syntactic definitions of the
      arguments.

      
         Messages with message sequence numbers corresponding to the

Sets a flag for a single message on the IMAP server. If value = 1, the flag is turned on, if value = 0, the flag is turned off. Standard system flags such as "\Deleted", "\Seen", "\Answered", "\Flagged", "\Draft", and "\Answered" may be set. Custom flags such as "NonJunk", "$label1", "$MailFlagBit1", etc. may also be set.

If bUid is .T., then msgId represents a UID. If bUid is .F., then msgId represents a sequence number.

Returns .T. for success, .F. for failure.

Creates an asynchronous task to call the SetFlags method with the arguments provided. (Async methods are available starting in Chilkat v9.5.0.52.)

Returns .F. on failure

top

Sets a flag for a single message on the IMAP server. The UID of the email object is used to find the message on the IMAP server that is to be affected. If value = 1, the flag is turned on, if value = 0, the flag is turned off.

Both standard system flags as well as custom flags may be set. Standard system flags typically begin with a backslash character, such as "\Deleted", "\Seen", "\Answered", "\Flagged", "\Draft", and "\Answered". Custom flags can be anything, such as "NonJunk", "$label1", "$MailFlagBit1", etc. .

Note: When the Chilkat IMAP component downloads an email from an IMAP server, it inserts a "ckx-imap-uid" header field in the email object. This is subsequently used by this method to get the UID associated with the email. The "ckx-imap-uid" header must be present for this method to be successful.

Note: Calling this method is identical to calling the SetFlag method, except the UID is automatically obtained from the email object.

Important: Setting the "Deleted" flag does not remove the email from the mailbox. Emails marked "Deleted" are removed when the Expunge method is called.

Returns .T. for success, .F. for failure.

top

Sets the quota for a quotaRoot. The resource should be one of two keywords:"STORAGE" or "MESSAGE". Use "STORAGE" to set the maximum capacity of the combined messages in quotaRoot. Use "MESSAGE" to set the maximum number of messages allowed.

If setting a STORAGE quota, the quota is in units of 1024 octets. For example, to specify a limit of 500,000,000 bytes, set quota equal to 500,000.

This feature is only possible with IMAP servers that support the QUOTA extension/capability. If an IMAP server supports the QUOTA extension, it likely supports the STORAGE resource. The MESSAGE resource is less commonly supported.

Specifies a client-side certificate to be used for the SSL / TLS connection. In most cases, servers do not require client-side certificates for SSL/TLS. A client-side certificate is typically used in high-security situations where the certificate is an additional means to indentify the client to the server.

Returns .T. for success, .F. for failure.

(Same as SetSslClientCert, but allows a .pfx/.p12 file to be used directly) Specifies a client-side certificate to be used for the SSL / TLS connection. In most cases, servers do not require client-side certificates for SSL/TLS. A client-side certificate is typically used in high-security situations where the certificate is an additional means to indentify the client to the server.

The pemDataOrFilename may contain the actual PEM data, or it may contain the path of the PEM file. This method will automatically recognize whether it is a path or the PEM data itself.

Searches the already selected mailbox for messages that match searchCriteria and returns a message set of all matching messages in the order specified by sortCriteria. If bUid is .T., then UIDs are returned in the message set, otherwise sequence numbers are returned.

The sortCriteria is a string of SPACE separated keywords to indicate sort order (default is ascending). The keyword "REVERSE" can precede a keyword to reverse the sort order (i.e. make it descending). Possible sort keywords are:

• ARRIVAL
• CC
• DATE
• FROM
• SIZE
• SUBJECT
• TO

Some examples of sortCriteria are:

• "SUBJECT REVERSE DATE"
• "REVERSE SIZE"
• "ARRIVAL"

The searchCriteria is passed through to the low-level IMAP protocol unmodified, and therefore the rules for the IMAP SEARCH command (RFC 3501) apply. See the documentation for the Search method for more details (and also see RFC 3501).

Returns .F. on failure

Authenticates with the SSH server using public-key authentication. The corresponding public key must have been installed on the SSH server for the sshLogin. Authentication will succeed if the matching privateKey is provided.

Important: When reporting problems, please send the full contents of the LastErrorText property to support@chilkatsoft.com.

Returns .T. for success, .F. for failure.

Creates an asynchronous task to call the SshAuthenticatePk method with the arguments provided. (Async methods are available starting in Chilkat v9.5.0.52.)

Returns .F. on failure

top

Authenticates with the SSH server using a sshLogin and sshPassword.

An SSH tunneling (port forwarding) session always begins by first calling SshTunnel to connect to the SSH server, then calling either AuthenticatePw or AuthenticatePk to authenticate. Following this, your program should call Connect to connect with the IMAP server (via the SSH tunnel) and then Login to authenticate with the IMAP server.

Note: Once the SSH tunnel is setup by calling SshTunnel and SshAuthenticatePw (or SshAuthenticatePk), all underlying communcations with the IMAP server use the SSH tunnel. No changes in programming are required other than making two initial calls to setup the tunnel.

Connects to an SSH server and creates a tunnel for IMAP. The sshHostname is the hostname (or IP address) of the SSH server. The sshPort is typically 22, which is the standard SSH port number.

An SSH tunneling (port forwarding) session always begins by first calling SshOpenTunnel to connect to the SSH server, followed by calling either SshAuthenticatePw or SshAuthenticatePk to authenticate. Your program would then call Connect to connect with the IMAP server (via the SSH tunnel) and then Login to authenticate with the IMAP server.

Sets one or more flags to a specific value for an email. The email is indicated by either a UID or sequence number, depending on whether bUid is .T. (UID) or .F. (sequence number).

flagNames should be a space separated string of flag names. Both standard and customer flags may be set. Standard flag names typically begin with a backslash character. For example: "\Seen \Answered". Custom flag names may also be included. Custom flags often begin with a $ character, such as "$label1", or "$MailFlagBit0". Other customer flags may begin with any character, such as "NonJunk".

value should be 1 to turn the flags on, or 0 to turn the flags off.

Sends the THREAD command to search the already selected mailbox for messages that match searchCriteria.

The following explanation is from RFC 5256 :

The THREAD command is a variant of SEARCH with threading semantics 
for the results.  Thread has two arguments before the searching 
criteria argument: a threading algorithm and the searching 
charset.

The THREAD command first searches the mailbox for messages that
match the given searching criteria using the charset argument for
the interpretation of strings in the searching criteria.  It then
returns the matching messages in an untagged THREAD response,
threaded according to the specified threading algorithm.

All collation is in ascending order.  Earlier dates collate before
later dates and strings are collated according to ascending values.

The defined threading algorithms are as follows:

      ORDEREDSUBJECT

         The ORDEREDSUBJECT threading algorithm is also referred to as
         "poor man's threading".  The searched messages are sorted by
         base subject and then by the sent date.  The messages are then
         split into separate threads, with each thread containing
         messages with the same base subject text.  Finally, the threads
         are sorted by the sent date of the first message in the thread.

         The top level or "root" in ORDEREDSUBJECT threading contains
         the first message of every thread.  All messages in the root
         are siblings of each other.  The second message of a thread is
         the child of the first message, and subsequent messages of the
         thread are siblings of the second message and hence children of
         the message at the root.  Hence, there are no grandchildren in
         ORDEREDSUBJECT threading.

         Children in ORDEREDSUBJECT threading do not have descendents.
         Client implementations SHOULD treat descendents of a child in a
         server response as being siblings of that child.

      REFERENCES

         The REFERENCES threading algorithm threads the searched
         messages by grouping them together in parent/child
         relationships based on which messages are replies to others.
         The parent/child relationships are built using two methods:
         reconstructing a message's ancestry using the references
         contained within it; and checking the original (not base)
         subject of a message to see if it is a reply to (or forward of)
         another message.

See RFC 5256 for more details:

The searchCriteria is passed through to the low-level IMAP protocol unmodified, and therefore the rules for the IMAP SEARCH command (RFC 3501) apply. See the documentation for the Search method for more details (and also see RFC 3501).

The results are returned in a JSON object to make it easy to parse the parent/child relationships. See the example below for details.

Adds an XML certificate vault to the object's internal list of sources to be searched for certificates and private keys when encrypting/decrypting or signing/verifying. Unlike the AddPfxSourceData and AddPfxSourceFile methods, only a single XML certificate vault can be used. If UseCertVault is called multiple times, only the last certificate vault will be used, as each call to UseCertVault will replace the certificate vault provided in previous calls.

Returns .T. for success, .F. for failure.

Uses an existing SSH tunnel for the connection to the IMAP server. This method is identical to the UseSshTunnel method, except the SSH connection is obtained from an SSH object instead of a Socket object.

This is useful for sharing an existing SSH tunnel connection wth other objects. (SSH is a protocol where the tunnel contains many logical channels. IMAP connections can exist simultaneously with other connection within a single SSH tunnel as SSH channels.)

Returns .T. for success, .F. for failure.
