Chilkat.Imap PHP Reference

Chilkat.Imap

IMAP email component.

Object Creation

$obj = new COM("Chilkat.Imap");

Properties

bool AppendSeen

When true (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.

int AppendUid (read-only)

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.)

string AuthMethod

Can be set to "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.

string AuthzId

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

bool AutoUnwrapSecurity

When set to true, which is the default, security envelopes are automatically "unwrapped" when a message is retrieved from the server. Signed emails are automatically verified, and encrypted emails are automatically decrypted, restoring the email to the original state before signing and/or encrypting. Information about the signing and encrypting certificates can be retrieved from the Email object (methods: GetSignedByCert, GetEncryptedByCert; properties: SignedBy, EncryptedBy, SignaturesValid, Decrypted, ReceivedSigned, ReceivedEncrypted).

int ConnectTimeout

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

string ConnectedToHost (read-only)

Return true if currently connected to an IMAP server.

string Domain

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

int HeartbeatMs

This is the number of milliseconds between each AbortCheck event callback. The AbortCheck callback allows an application to abort any IMAP operation prior to completion. If HeartbeatMs is 0, no AbortCheck event callbacks will occur.

bool KeepSessionLog

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 false.

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

string LastAppendedMime (read-only)

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

string LastCommand (read-only)

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

string LastErrorHtml (read-only)

Returns the error log in HTML format for the last method called.Error information in HTML format for the last method called.

string LastErrorText (read-only)

Returns the error log in plain-text format for the last method called.Error information in plain-text format for the last method called.

string LastErrorXml (read-only)

Returns the error log in XML format for the last method called.Error information in XML format for the last method called.

string LastIntermediateResponse (read-only)

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

string LastResponse (read-only)

The raw data of the last response from the IMAP server. (Useful for debugging if problems occur.)

string LoggedInUser (read-only)

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

int NumMessages (read-only)

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

bool PeekMode

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.

int Port

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 = true.

int ReadTimeout

The amount of time in seconds to wait during a stall before timing out when reading from an IMAP server. The ReadTimeout is the amount of time that needs to elapse while no additional data is forthcoming. During a long data transfer, if the data stream halts for more than this amount, it will timeout.

The default value is 30 seconds.

string SelectedMailbox (read-only)

To be documented soon...

int SendBufferSize

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

string SeparatorChar

The separator character used by the IMAP server for the mailbox hierarchy.

string SessionLog (read-only)

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 true to enable session logging. Call ClearSessionLog to reset the log.

bool Ssl

true if the IMAP connection should be SSL.

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

bool SslServerCertVerified (read-only)

Read-only property that returns true if the IMAP server's digital certificate was verified when connecting via SSL / TLS.

string Version (read-only)

The version of the component, such as "1.0.0".

Methods

bool AppendMail(string mailbox, Chilkat.Email mailObject)

Appends an email to an IMAP mailbox.

Returns 1 for success, 0 for failure.

bool AppendMime(string mailbox, string mimeText)

Appends an email (represented as MIME text) to an IMAP mailbox.

Returns 1 for success, 0 for failure.

bool AppendMimeWithDate(string mailbox, string mimeText, Date internalDate)

To be documented soon.

bool AppendMimeWithFlags(string mailbox, string mimeText, int seen, int flagged, int answered, int draft)

Same as AppendMime, but allows the flags associated with the email to be set at the same time. A flag is on if true, and off if false.

Returns 1 for success, 0 for failure.

void ClearSessionLog()

Clears the contents of the SessionLog property.

bool Connect(string hostname)

Connects to an IMAP server, but does not login.

Returns 1 for success, 0 for failure.

bool Copy(int msgId, int bUid, string copyToMailbox)

Copies a message from the selected mailbox to copyToMailbox. If bUid is true, then msgId represents a UID. If bUid is false, then msgId represents a sequence number.

Returns 1 for success, 0 for failure.

bool CopyMultiple(Chilkat.MessageSet messageSet, string copyToMailbox)

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

Returns 1 for success, 0 for failure.

bool CopySequence(int startSeqNum, int count, string copyToMailbox)

Copies one or more emails from one mailbox to another. The emails are specified as a range of sequence numbers. The 1st email in a mailbox is always at sequence number 1.

Returns 1 for success, 0 for failure.

bool CreateMailbox(string mailbox)

Creates a new mailbox.

Returns 1 for success, 0 for failure.

bool DeleteMailbox(string mailbox)

Deletes an existing mailbox.

Returns 1 for success, 0 for failure.

void Disconnect()

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 1 for success, 0 for failure.

bool ExamineMailbox(string mailbox)

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.

Returns 1 for success, 0 for failure.

bool Expunge()

Permanently removes from the currently selected mailbox all messages that have the Deleted flag set.

Returns 1 for success, 0 for failure.

Returns 1 for success, 0 for failure.

Chilkat.EmailBundle FetchBundle(Chilkat.MessageSet messageSet)

Retrieves a set of messages from the IMAP server and returns them in an email bundle object. If the method fails, it may return a NULL reference.

Returns a null reference on failure

Chilkat.StringArray FetchBundleAsMime(Chilkat.MessageSet messageSet)

Retrieves a set of messages from the IMAP server and returns them in a string array object (NOTE: it does not return a string array, but an object that represents a string array.) Each string within the returned object is the complete MIME source of an email. On failure, a NULL object reference is returned.

Returns a null reference on failure

string FetchFlags(int msgId, int bUid)

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

Returns a null on failure

Chilkat.EmailBundle FetchHeaders(Chilkat.MessageSet messageSet)

Retrieves a set of message headers from the IMAP server and returns them in an email bundle object. If the method fails, it may return a NULL reference. The following methods are useful for retrieving information about attachments and flags after email headers are retrieved: GetMailNumAttach, GetMailAttachSize, GetMailAttachFilename, GetMailFlag.

Returns a null reference on failure

Chilkat.EmailBundle FetchSequence(int startSeqNum, int numMessages)

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.

Returns a null reference on failure

Chilkat.StringArray FetchSequenceAsMime(int startSeqNum, int numMessages)

Same as FetchSequence, but instead of returning email objects in a bundle, the raw MIME of each email is returned.

Returns a null reference on failure

Chilkat.EmailBundle FetchSequenceHeaders(int startSeqNum, int numMessages)

Same as FetchSequence, but only the email headers are returned. The email objects within the bundle will be lacking bodies and attachments.

Returns a null reference on failure

Chilkat.Email FetchSingle(int msgId, int bUID)

Retrieves a single message from the IMAP server. If the method fails, it may return a NULL reference. If bUid is true, then msgID represents a UID. If bUid is false, then msgID represents a sequence number.

Returns a null reference on failure

string FetchSingleAsMime(int msgId, int bUID)

Retrieves a single message from the IMAP server and returns a string containing the complete MIME source of the email. If the method fails, it returns a NULL reference. If bUid is true, then msgID represents a UID. If bUid is false, then msgID represents a sequence number.

Returns a null on failure

Chilkat.Email FetchSingleHeader(int msgId, int bUID)

Retrieves a single message header from the IMAP server. If the method fails, it may return a NULL reference. The following methods are useful for retrieving information about attachments and flags after an email header is retrieved: GetMailNumAttach, GetMailAttachSize, GetMailAttachFilename, GetMailFlag. If bUid is true, then msgID represents a UID. If bUid is false, then msgID represents a sequence number.

Returns a null reference on failure

string FetchSingleHeaderAsMime(int msgId, int bUID)

Fetches and returns the MIME of a single email header.

Returns a null on failure

Chilkat.MessageSet GetAllUids()

Returns a message set object containing all the UIDs in the currently selected mailbox. A NULL object reference is returned on failure.

Returns a null reference on failure

string GetMailAttachFilename(Chilkat.Email mail, int index)

Returns the Nth attachment filename. Indexing begins at 0.

int GetMailNumAttach(Chilkat.Email email)

Returns the number of email attachments.

int GetMailSize(Chilkat.Email mail)

Returns the size (in bytes) of the entire email including attachments.

Chilkat.Cert GetSslServerCert()

Returns the IMAP server's digital certificate (for SSL / TLS connections).

bool IsConnected()

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.

bool IsLoggedIn()

Returns true if already logged into an IMAP server, otherwise returns false.

Chilkat.Mailboxes ListMailboxes(string reference, string wildcardedMailbox)

Returns a subset of the complete list of mailboxes available on the IMAP server. The reference and wildcardedMailbox parameters are passed unaltered to the IMAP LIST command:


FROM RFC 3501 (IMAP Protocol)

      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.

Returns a null reference on failure

bool Login(string login, string password)

Logs into the IMAP server. The component must first be connected to an IMAP server by calling Connect.

bool Logout()

Logs out of the IMAP server.

int Noop()

Sends a NOOP command to the IMAP server and receives the response. The component must be connected and authenticated for this to succeed. Sending a NOOP is a good way of determining whether the connection to the IMAP server is up and active.

Returns 1 for success, 0 for failure.

bool RefetchMailFlags(Chilkat.Email mailObject)

Fetches the flags for an email and updates the flags in the email's header. When an email is retrieved from the IMAP server, it embeds the flags into the header in fields beginning with "ckx-". Methods such as GetMailFlag and GetWebMailFlag read these header fields.

bool RenameMailbox(string fromMailbox, string toMailbox)

Renames a mailbox.

void SaveLastError(string filename)

Saves the last error information to an XML formatted file.

Chilkat.MessageSet Search(string criteria, int bUID)

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


FROM RFC 3501 (IMAP Protocol)

      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
         specified message sequence number set.

bool SelectMailbox(string mailbox)

Selects a mailbox. A mailbox must be selected before some methods, such as Search or FetchSingle, can be called. If the logged-on user does not have write-access to the mailbox, call ExamineMailbox instead.

Returns 1 for success, 0 for failure.

string SendRawCommand(string cmd)

Allows for the sending of arbitrary commands to the IMAP server.

Returns a null on failure

bool SetDecryptCert2(Chilkat.Cert iCert, Chilkat.PrivateKey iKey)

To be documented soon...

bool SetFlag(int msgId, int bUid, string flagName, int value)

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. Valid flag names are "Seen", "Answered", "Draft", "Flagged", and "Deleted".

If bUid is true, then msgId represents a UID. If bUid is false, then msgId represents a sequence number.

Returns 1 for success, 0 for failure.

bool SetFlags(Chilkat.MessageSet messageSet, string flagName, int value)

Sets a flag for each message in the message set on the IMAP server. If value = 1, the flag is turned on, if value = 0, the flag is turned off. Valid flag names are "Seen", "Answered", "Draft", "Flagged", and "Deleted".

Returns 1 for success, 0 for failure.

bool SetMailFlag(Chilkat.Email email, string flagName, int value)

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.

Valid flag names are "Seen", "Answered", "Draft", "Flagged", and "Deleted".

Returns 1 for success, 0 for failure.

void SetSslClientCert(Chilkat.Cert iCert)

Allows for a client-side certificate to be used for the SSL / TLS connection.

int SshAuthenticatePk(string sshLogin, Chilkat.SshKey privateKey)

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 1 for success, 0 for failure.

int SshAuthenticatePw(string sshLogin, string sshPassword)

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.

Returns 1 for success, 0 for failure.

int SshTunnel(string sshServerHostname, int sshPort)

Connects to an SSH server and creates a tunnel for IMAP. The sshServerHostname 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 SshTunnel to connect to the SSH server, followed by calling either AuthenticatePw or AuthenticatePk 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.

bool StoreFlags(int msgId, int bUid, string flagNames, int value)

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 true (UID) or false (sequence number).

flagNames should be a space separated string of flag names, where each flag name begins with a backslash character. For example: "\Seen \Answered". Possible flag names are \Seen, \Answered, \Flagged, \Deleted, and \Draft.

Note: The other methods, such as SetFlag, SetFlags, and SetMailFlag, require flag names without the leading backslash.

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

Returns 1 for success, 0 for failure.

bool Subscribe(string mailbox)

Subscribe to an IMAP mailbox.

Returns 1 for success, 0 for failure.

bool UnlockComponent(string unlockCode)

Unlocks the component. This must be called once at the beginning of your program to unlock the component. A permanent unlock code is provided when the IMAP component is licensed. Any string, such as "Hello World", may be passed to this method to automatically begin a fully-functional 30-day trial.

Returns 1 for success, 0 for failure.

bool Unsubscribe(string mailbox)

Unsubscribe from an IMAP mailbox.

Returns 1 for success, 0 for failure.
