Irssi is a modular IRC client for UNIX that currently only has a text
mode user interface. However, 80-90% of the code is not text mode
specific, so other UIs could be created easily. Also, Irssi is not
really even IRC specific anymore. There are already working SILC and
ICB modules available. Support for other protocols, like ICQ and
Jabber, could be added some day, too.

It is the code that separates Irssi from ircII, BitchX, epic, and the
rest of the text clients. It is not using the ircII code.

ratbox-respond is a tool that provides a client side implementation of the
challenge opering system in ircd-ratbox. The challenge system provides the
ability to oper using private key authentication instead of passwords to
improve security.

ratbox-services is a services package written mostly from scratch for
use with ircd-ratbox.

It is highly configurable, with nearly all options being set in a
config that can be rehashed rather than set at compile time. It also
uses the SQLite database backend, which works as a database interface
to a normal file, meaning no seperate database software must be
running.

Username registration service
Allows users to register usernames, which then form the basis of all
access to channels.

Channel registration services
Allows users to maintain channels, with access levels from 1 to 200.
Nickname registration service
Allows users to register nicknames, registered through a username.
Jupe service
Allows services operators to place jupes on servers, which prevents
the server from reconnecting to the network. Also contains an
optional method for ircops to vote upon jupes and unjupes.
Global message service
Allows services operators to send a message to all users on the
network.
Oper services
Allows services operators to perform mode changes in a channel, and
takeover channels.
Opered bot
The opered bot can be placed in channels, and will then invite or op
ircops in that channel upon request.
List service
Allows users to perform advanced searching of the list of channels.
Searching may take place on name, user count, topic and modes.

postfix, exim and the rest that drives email on the net.

ACL Policy Daemon is a program that communicates with the Postfix MTA using the
Policy Delegation Protocol implementing an ACL (Access Control List) system,
making very easy to improve and create nice controls on your e-mail traffic.
You can use it to verify SPF records to.

The logic behind apolicy is simple, you define some rules, then you combine
them, if all of them matches, apolicy will send an action for that combination,
defined by you to. Take a look on what you can apply rules using apolicy's
ACLs. Some of them you already can do with Postfix, but they are sequential. In
pure Postfix you can not combine rules.

It is developed using Python and has no other dependencies and licensed by GPL
version 2.

into the Maildir++ format used by the Courier-Imap and Dovecot IMAP servers.

fdm is a simple, lightweight replacement for mail fetch, filter and delivery

Gnarwl is an email autoresponder. Unlike the original vacation(1) program, gnarwl is based on LDAP. Traditionally you had to give every user, who wanted to use autoreply facilities full fledged system accounts (trusting them to set their forwarding up properly, cursing when they didn't). With gnarwl this is history. User information is now stored in LDAP. Thats right, no more messing around with system accounts or homedirs for users who just want their email working, but don't care to fuss around with shell commands.

isync is a command line application which synchronizes mailboxes; currently
Maildir and IMAP4 mailboxes are supported. New messages, message deletions and
flag changes can be propagated both ways. isync is suitable for use in
IMAP-disconnected mode.

Synchronization is based on unique message identifiers (UIDs), so no
identification conflicts can occur (as opposed to some other mail
synchronizers). Synchronization state is kept in one local text file per
mailbox pair; multiple replicas of a mailbox can be maintained.

mpop is a small and fast POP3 client. Features include mail filtering, delivery to mbox files, maildir folders or a mail delivery agent, a very fast POP3 implementation, many authentication methods, good TLS/SSL support, IPv6 support, and more.

msmtp is an SMTP client that can be used as a plug-in for Mutt and
other mail user agents. It forwards mail to an SMTP server that does
the delivery. Supports multiple accounts.

Mutt next generation (mutt-ng) is a fork of the well-known email client
mutt with the goal to both incorporate all the patches that are
floating around in the web, and to fix all the other little annoyances
of mutt.
