Mail::IMAPTalk is an IMAP client interface with lots of features.

SYNOPSIS

use Mail::IMAPTalk;

$IMAP = Mail::IMAPTalk->new(
Server => $IMAPServer,
Username => foo,
Password => bar,
Uid => 1 )
|| die "Failed to connect/login to IMAP server";

# Append message to folder
open(my $F, rfc822msg.txt);
$IMAP->append($FolderName, $F) || dir $@;
close($F);

# Select folder and get first unseen message
$IMAP->select($FolderName) || die $@;
$MsgId = $IMAP->search(not, seen)->[0];

# Get message envelope and print some details
$MsgEV = $IMAP->fetch($MsgId, envelope)->{$MsgId}->{envelope};
print "From: " . $MsgEv->{From};
print "To: " . $MsgEv->{To};
print "Subject: " . $MsgEv->{Subject};

# Get message body structure
$MsgBS = $IMAP->fetch($MsgId, bodystructure)->{$MsgId}->{bodystructure};

# Find imap part number of text part of message
$MsgTxtHash = Mail::IMAPTalk::find_message($MsgBS);
$MsgPart = $MsgTxtHash->{plain}->{IMAP-Partnum};

# Retrieve message text body
$MsgTxt = $IMAP->fetch($MsgId, "body[$MsgPart]")->{$MsgId}->{body};

$IMAP->logout();

This module communicates with an IMAP server. Each IMAP server command is mapped to a method of this object.

Although other IMAP modules exist on CPAN, this has several advantages over other modules.

It parses the more complex IMAP structures like envelopes and body structures into nice Perl data structures.

It correctly supports atoms, quoted strings and literals at any point. Some parsers in other modules arent fully IMAP compatiable and may break at odd times with certain messages on some servers.

It allows large return values (eg. attachments on a message) to be read directly into a file, rather than into memory.

It includes some helper functions to find the actual text/plain or text/html part of a message out of a complex MIME structure. It also can find a list of attachements, and CID links for HTML messages with attached images.

It supports decoding of MIME headers to Perl utf-8 strings automatically, so you dont have to deal with MIME encoded headers (enabled optionally).

While the IMAP protocol does allow for asynchronous running of commands, this module is designed to be used in a synchronous manner. That is, you issue a command by calling a method, and the command will block until the appropriate response is returned. The method will then return the parsed results from the given command.

OfflineIMAP is a tool to simplify your e-mail reading. With OfflineIMAP, you can read the same mailbox from multiple computers. You get a current copy of your messages on each computer, and changes you make one place will be visible on all other systems.

For instance, you can delete a message on your home computer, and it will appear deleted on your work computer as well. OfflineIMAP is also useful if you want to use a mail reader that does not have IMAP support, has poor IMAP support, or does not provide disconnected operation.

OfflineIMAP works on pretty much any POSIX operating system, such as Linux, BSD operating systems, Solaris, etc.

OfflineIMAP is a Free Software project licensed under the GNU General Public License. You can download it for free, and you can modify it. In fact, you are encouraged to contribute to OfflineIMAP, and doing so is fast and easy.

imapbiff checks IMAP accounts for new mail. It uses images similar to those of the classic xbiff program. The project works similar to xbiff, except it is only used to check for new mail in IMAP accounts.

It is written in perl, and requires the Tk module for perl. It was written spefically to be docked in my fvwm2 button bar, as I could not find a simple xbiff like app that would do IMAP checks.

Citadel is an advanced messaging and collaboration system for groupware and BBS applications. Users can connect to Citadel using any telnet, WWW, or client software.
Among the features supported are public and private message bases (rooms), electronic mail, real-time chat, paging, shared calendaring, address books, mailing lists, and more.
Unlike other collaboration servers, Citadel provides its own data stores and is therefore extremely easy to install; you dont have to "bring your own" email and database because theyre built in.
The server is multithreaded and scalable. In addition, SMTP, IMAP, and POP3 servers are built-in for easy connection to Internet mail. Citadel is both robust and mature; it has been in production since 1987.
Enhancements:
- IMAP ACL support.
- Small enhancements to the calendar service.
- Enhanced support for certain text-mode mobile devices.

Openmailadmin is a little administration interface to every complete IMAP mail server daemon. Openmailadmin supports every feature IMAP provides, and fits in most MTA configurations.
A key feature is the non-standard, generic administration hierarchy which not only seperates "normal users" from "administrators", but enables the mailserver-master to create instances between them.
You will be able to let other users create their own sub-users and thus either share a single mail server between different organizations or project your companys employee structure. It excels with features such as regex addresses and folder ACL management.
Installation:
1. Copy all the files into your DocumentRoot-folder.
2. Modify following files by changing usernames and passwords:
- samples/pam/imap
- inc/database.sql
And either of these:
- samples/postfix/*
- samples/oma_mail.daimon.*
3. Create the required database and users in MySQL. Modify database.sql and have it executed inside the new database.
4. Copy samples/pam/imap settings to your /etc/pam.d folder
{{{
chmod 600 samples/pam/imap
cp samples/pam/imap /etc/pam.d/imap
ln -s /etc/pam.d/imap /etc/pam.d/pop
ln -s /etc/pam.d/imap /etc/pam.d/sieve
ln -s /etc/pam.d/imap /etc/pam.d/smtp
}}}
5. For security reasons, remove these files from your DocumentRoot-folder:
{{{
rm inc/database.sql
rm -r samples/pam
rm samples/oma_mail.daimon.* samples/postfix
}}}
