CkImap
IMAP email component.
Object Creation
obj = chilkat.CkImap()
Properties
# Returns a boolean value
get_AppendSeen( )
# alreadySeen is a boolean (input)
put_AppendSeen( alreadySeen )
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.
# Returns an integer value
get_AppendUid( )
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.)
# str is a CkString object (output)
get_AuthMethod( str )
# str is a string (input)
put_AuthMethod( str )
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.
# str is a CkString object (output)
get_AuthzId( str )
# newVal is a string (input)
put_AuthzId( newVal )
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.
# Returns a boolean value
get_AutoUnwrapSecurity( )
# bUnwrap is a boolean (input)
put_AutoUnwrapSecurity( bUnwrap )
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).

# reference is a string (input)
# wildcardedMailbox is a string (input)
# Returns a CkMailboxes object
ListMailboxes( reference, 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
# login is a string (input)
# password is a string (input)
# Returns a boolean value
Login( login, password )
Logs into the IMAP server. The component must first be connected to an IMAP server by calling Connect.
# Returns a boolean value
Logout( )
Logs out of the IMAP server.
# Returns a boolean value
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 True for success, False for failure.
# emailInOut is a CkEmail object (output)
# Returns a boolean value
RefetchMailFlags( emailInOut )
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.
# fromMailbox is a string (input)
# toMailbox is a string (input)
# Returns a boolean value
RenameMailbox( fromMailbox, toMailbox )
Renames a mailbox.
# filename is a string (input)
# Returns a boolean value
SaveLastError( filename )
Saves the last error information to an XML formatted file.
# criteria is a string (input)
# bUid is a boolean (input)
# Returns a CkMessageSet object
Search( criteria, 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.
ALL
All messages in the mailbox; the default initial key for
ANDing.

FLAGGED
Messages with the \Flagged flag set.
FROM
Messages that contain the specified string in the envelope
structure's FROM field.
HEADER
Messages that have a header with the specified field-name (as
defined in [RFC-2822]) and that contains the specified string
in the text of the header (what comes after the colon). If the
string to search is zero-length, this matches all messages that
have a header line with the specified field-name regardless of
the contents.

Returns a null reference on failure
# mailbox is a string (input)
# Returns a boolean value
SelectMailbox( 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 True for success, False for failure.
# rawCommand is a string (input)
# rawResponse is a CkString object (output)
# Returns a boolean value
SendRawCommand( rawCommand, rawResponse )
Allows for the sending of arbitrary commands to the IMAP server. Returns True for success, False for failure.

# msgId is an integer (input)
# bUid is a boolean (input)
# flagName is a string (input)
# value is an integer (input)
# Returns a boolean value
SetFlag( msgId, bUid, flagName, 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 True for success, False for failure.
# messageSet is a CkMessageSet object (input)
# flagName is a string (input)
# value is an integer (input)
# Returns a boolean value
SetFlags( messageSet, flagName, 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 True for success, False for failure.
# email is a CkEmail object (input)
# flagName is a string (input)
# value is an integer (input)
# Returns a boolean value
SetMailFlag( email, flagName, 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".
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. Returns True for success, False for failure.
SetSslClientCert( cert )
Allows for a client-side certificate to be used for the SSL / TLS connection.
# pfxFilename is a string (input)
# pfxPassword is a string (input)

To be documented soon...
# sshLogin is a string (input)
# Returns a boolean value
SshAuthenticatePk( sshLogin, 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 True for success, False for failure.
# sshLogin is a string (input)
# sshPassword is a string (input)
# Returns a boolean value
SshAuthenticatePw( sshLogin, 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.
Important: When reporting problems, please send the full contents of the LastErrorText property to support@chilkatsoft.com. Returns True for success, False for failure. IMAP SSH Tunneling (Port Forwarding)
# sshServerHostname is a string (input)
# sshPort is an integer (input)
# Returns a boolean value
SshTunnel( sshServerHostname, 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.

StoreFlags( msgId, bUid, flagNames, 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 True for success, False for failure.
