Openmailadmin is a little administration interface to every complete IMAP mail server daemon. It 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 company's employee structure. It excels with features such as regex addresses and folder ACL management.

Perdition is a fully featured POP3 and IMAP4 proxy server. It is able to handle both SSL and non-SSL connections and redirect users to a real-server based on a database lookup. Perdition supports modular based database access. The distribution ships with modules for ODBC, MySQL, PostgreSQL, GDBM, POSIX Regular Expression, and NIS. The API for modules is open, allowing abitary modules to be written to allow access to any data store. Perdition can be used to create large mail systems where an end-user's mailbox may be stored on one of several hosts, to integrate different mail systems together, to migrate between different email infrastructures, and to bridge plain-text, SSL, and TLS services. It can also be used as part of a firewall.

TWIG is a Web-based groupware suite written in
PHP, compatible with both PHP3 and PHP4. Its
features include IMAP and POP3 email, Usenet
newsgroups, contact management, scheduling, shared
notes and bookmarks, a todo list, and meeting
announcements. Any piece of information can be
shared with others via group oriented access
controls. By using only plain HTML, it is a
simple, cross-platform, fast, and
browser-independent way to access or share almost
any kind of information, without the complexity or
costs of other intranet/groupware packages. It is
fully internationalized, with 24 translations.

The IMAP Proxy server is a caching IMAP proxy
server. It was written to reduce the load that
Webmail clients put on an IMAP server by keeping
server connections alive for reuse, thus avoiding
a new server connection for each Webmail transaction.

OverLook is a Web mail client forked from the SquirrelMail project. It attempts to change the look and feel and make it simpler to use.

IndiMail is a messaging platform built using qmail and other messaging software. IndiMail has the ability to distribute the users in a domain across multiple hosts. IndiMail has multiple queues (called a queue collection), which can achiever very high concurrencies. The system IDs and configuration files used by IndiMail are all configurable through a set of environment variables, allowing you to customize IndiMail the way you want. IndiMail does not use hard-coded uid/gid in the executables, which makes it easy to distribute a binary package. IndiMail has features that any modern email server should have: SMTP, QMQP, QMTP, IMAP, POP3, DKIM, BATV, greylisting, filtering capability, and spam/virus control.

Virtual Exim is a PHP-enabled Web interface for managing multiple virtual mail domains with Exim and MySQL/PostgreSQL. POP/IMAP accounts, aliases, forwards, and permanent fail accounts can all be created and managed easily without the need for corresponding shell accounts. Virtual Exim also allows the server administrator to designate a SiteAdmin who can create and delete domains on the fly through the interface, so no editing of the Exim configuration file is required. Individual users can also log in to change their "Real Name", passwords, and mail filtering options with ease.

SmartSieve is a Web-based graphical user
interface for creating and managing sieve
scripts on a Cyrus IMAP mail server. It provides
a way for non-technical users to generate

and is intended to be intuitive to use and
simple to configure, and is compatible with
Websieve scripts.

Decimail Server is a mail server supporting IMAP
and SMTP that uses a PostgreSQL database to store
messages. Mailboxes are defined using SQL queries,
allowing complex client-independent automatic
message filtering and categorisation. For example
you can partition your messages chronologically,
by correspondent, and by mailing list at the same
time, with each message appearing in several
mailboxes. You can also use PostgreSQL's text indexing
extension for fast keyword searching. Decimail also features anti-spam processing of outgoing messages.

isync is a commandline application which synchronizes a local maildir-style mailbox with a remote IMAP4 mailbox, suitable for use in IMAP-disconnected mode. Multiple copies of the remote IMAP4 mailbox can be maintained, and all flags are synchronized. TLS/SSL is supported via imaps: or STARTTLS.
