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.
