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.
