NAME

       Cyrus::IMAP - Interface to Cyrus imclient library

SYNOPSIS

	 use Cyrus::IMAP;

	 my $client = Cyrus::IMAP->new('mailhost'[, $flags]);
	 $flags = Cyrus::IMAP::CONN_NONSYNCLITERAL;

	 ($server, $mailbox) = Cyrus::IMAP->fromURL($url);
	 $url = Cyrus::IMAP->toURL($server, $mailbox);

	 $client->setflags($flags);
	 $client->clearflags(Cyrus::IMAP::CONN_INITIALRESPONSE);
	 $flags = $client->flags;
	 $server = $client->servername;
	 $client->authenticate;
	 $flags = Cyrus::IMAP::CALLBACK_NUMBERED || Cyrus::IMAP::CALLBACK_NOLITERAL;
	 $client->addcallback({-trigger => $str, -flags => $flags,
			       -callback => &cb, -rock => $var}, ...);
	 $client->send(&callback, &cbdata, $format, ...);
	 $client->processoneevent;
	 ($result, $text) = $client->send(undef, undef, $format, ...);
	 ($fd, $writepending) = $client->getselectinfo;

DESCRIPTION

       The Cyrus::IMAP module provides an interface to the Cyrus imclient library.  These are primarily useful for implementing cyradm operations
       within a Perl script; there are easier ways to implement general client operations, although they may be more limited in terms of
       authentication options when talking to a Cyrus imapd.

       In the normal case, one will attach to a Cyrus server and authenticate using the best available method:

	       my $client = Cyrus::IMAP::new('imap');
	       $client->authenticate;
	       if (!$client->send('', '', 'CREATE %s', 'user.' . $username)) {
		 warn "createmailbox user.$username: $@";
	       }

       In simple mode as used above, "send()" is invoked with "undef", 0, or '' for the callback and rock (callback data) arguments; it returns a
       list of "($result, $text)" from the command.  If invoked in scalar context, it returns $result and places $text in $@.  In this mode, there
       is no need to use "processoneevent()".  If more control is desired, use the callback and rock arguments and invoke "processoneevent()"
       regularly to receive results from the IMAP server.  If still more control is needed, the "getselectinfo()" method returns a list containing
       a file descriptor (not Perl filehandle) which can be passed to select(); if the second element of the list is true, you should include it
       in the write mask as well as the read mask because the imclient library needs to perform queued output.

       For more information, consult the Cyrus documentation.

NOTES

       "send()" behaves as if the "Cyrus::IMAP::CONN_NONSYNCLITERAL" flag is always set.  This is because it is a wrapper for the C version, which
       cannot be made directly available from Perl, and synchronous literals require interaction with the IMAP server while parsing the format
       string.	This is planned to be fixed in the future.

       The 'LOGIN' mechanism can be used to authenticate with a plaintext username and password.  This is intended as a workaround for a bug in
       early SASL implementations; use of Cyrus::IMAP with non-Cyrus servers is not recommended, primarily because there are easier ways to
       implement IMAP client functionality in Perl.  (However, if you need SASL support, "Cyrus::IMAP" is currently the only way to get it.)

       The file descriptor returned by "getselectinfo()" should not be used for anything other than "select()".  In particular, I/O on the file
       descriptor will almost certainly cause more problems than whatever problem you think you are trying to solve.

       The toURL and fromURL routines are to ease conversion between URLs and IMAP mailbox and server combinations, and are a simple frontend for
       the libcyrus functions of the same name.

       The imparse library routines are not implemented, because they are little more than a (failed) attempt to make parsing as simple in C as it
       is in Perl.

       This module exists primarily so we can integrate Cyrus administration into our Perl-based account management system, and secondarily so
       that we can rewrite cyradm in a sensible language instead of Tcl.  Usability for other purposes is not guaranteed.
