SYNOPSIS

9         use Cyrus::IMAP;
10
11         my $client = Cyrus::IMAP->new('mailhost'[, $flags]);
12         $flags = Cyrus::IMAP::CONN_NONSYNCLITERAL;
13
14         ($server, $mailbox) = Cyrus::IMAP->fromURL($url);
15         $url = Cyrus::IMAP->toURL($server, $mailbox);
16
17         $client->setflags($flags);
18         $client->clearflags(Cyrus::IMAP::CONN_INITIALRESPONSE);
19         $flags = $client->flags;
20         $server = $client->servername;
21         $client->authenticate;
22         $flags = Cyrus::IMAP::CALLBACK_NUMBERED || Cyrus::IMAP::CALLBACK_NOLITERAL;
23         $client->addcallback({-trigger => $str, -flags => $flags,
24                               -callback => \&cb, -rock => \$var}, ...);
25         $client->send(\&callback, \&cbdata, $format, ...);
26         $client->processoneevent;
27         ($result, $text) = $client->send(undef, undef, $format, ...);
28         ($fd, $writepending) = $client->getselectinfo;

DESCRIPTION

31       The Cyrus::IMAP module provides an interface to the Cyrus imclient
32       library.  These are primarily useful for implementing cyradm operations
33       within a Perl script; there are easier ways to implement general client
34       operations, although they may be more limited in terms of
35       authentication options when talking to a Cyrus imapd.
36
37       In the normal case, one will attach to a Cyrus server and authenticate
38       using the best available method:
39
40               my $client = Cyrus::IMAP::new('imap');
41               $client->authenticate;
42               if (!$client->send('', '', 'CREATE %s', 'user.' . $username)) {
43                 warn "createmailbox user.$username: $@";
44               }
45
46       In simple mode as used above, "send()" is invoked with "undef", 0, or
47       '' for the callback and rock (callback data) arguments; it returns a
48       list of "($result, $text)" from the command.  If invoked in scalar
49       context, it returns $result and places $text in $@.  In this mode,
50       there is no need to use "processoneevent()".  If more control is
51       desired, use the callback and rock arguments and invoke
52       "processoneevent()" regularly to receive results from the IMAP server.
53       If still more control is needed, the "getselectinfo()" method returns a
54       list containing a file descriptor (not Perl filehandle) which can be
55       passed to select(); if the second element of the list is true, you
56       should include it in the write mask as well as the read mask because
57       the imclient library needs to perform queued output.
58
59       For more information, consult the Cyrus documentation.

NOTES

62       "send()" behaves as if the "Cyrus::IMAP::CONN_NONSYNCLITERAL" flag is
63       always set.  This is because it is a wrapper for the C version, which
64       cannot be made directly available from Perl, and synchronous literals
65       require interaction with the IMAP server while parsing the format
66       string.  This is planned to be fixed in the future.
67
68       The 'LOGIN' mechanism can be used to authenticate with a plaintext
69       username and password.  This is intended as a workaround for a bug in
70       early SASL implementations; use of Cyrus::IMAP with non-Cyrus servers
71       is not recommended, primarily because there are easier ways to
72       implement IMAP client functionality in Perl.  (However, if you need
73       SASL support, "Cyrus::IMAP" is currently the only way to get it.)
74
75       The file descriptor returned by "getselectinfo()" should not be used
76       for anything other than "select()".  In particular, I/O on the file
77       descriptor will almost certainly cause more problems than whatever
78       problem you think you are trying to solve.
79
80       The toURL and fromURL routines are to ease conversion between URLs and
81       IMAP mailbox and server combinations, and are a simple frontend for the
82       libcyrus functions of the same name.
83
84       The imparse library routines are not implemented, because they are
85       little more than a (failed) attempt to make parsing as simple in C as
86       it is in Perl.
87
88       This module exists primarily so we can integrate Cyrus administration
89       into our Perl-based account management system, and secondarily so that
90       we can rewrite cyradm in a sensible language instead of Tcl.  Usability
91       for other purposes is not guaranteed.
