ngIRCd is a free, portable and lightweight Internet Relay Chat server
for small or private networks, developed under the GNU General Public
License. It is simple to configure, can cope with dynamic IP addresses,
and supports IPv6 as well as SSL. It is written from scratch and not
based on the original IRCd.
DavMail POP/IMAP/SMTP/Caldav/Carddav/LDAP Exchange Gateway
DavMail is a POP/IMAP/SMTP/Caldav/Carddav/LDAP exchange gateway
allowing users to use any mail/calendar client (e.g. Thunderbird
with Lightning or Apple iCal) with an Exchange server, even from
the internet or behind a firewall through Outlook Web Access.
DSPAM (as in De-Spam) is an open-source project to create a new kind
of anti-spam mechanism, and is currently effective as both a
server-side agent for UNIX email servers and a developer's library
for mail clients, other anti-spam tools, and similar projects
requiring drop-in spam filtering.
fdm is a simple, lightweight replacement for mail fetch, filter and
delivery programs such as fetchmail and procmail. It can currently
fetch using POP3, POP3S, IMAP or from stdin, and deliver to a pipe,
file, maildir, mbox or SMTP server, based on regexps.
Dovecot is a secure and compact IMAP server which is in the early stages
of development. It supports Maildirs and mbox formats and much of the
IMAP v4 protocol including SSL/TLS. IPv6 support is also included.
Dovecot supports authentication with OpenLDAP, PostgreSQL, MySQL, vpopmail
and PAM.
Twisted Mail contains high-level, efficient protocol implementations for both
clients and servers of SMTP, POP3, and IMAP4. Additionally, it contains an
"out of the box" combination SMTP/POP3 virtual-hosting mail server. Also
included is a read/write Maildir implementation and a basic Mail Exchange
calculator (depends on Twisted Names).
Twisted Mail is available under the MIT Free Software licence.
Pyzor is a collaborative, networked system to detect and block spam using
identifying digests of messages.
Pyzor initially started out to be merely a Python implementation of Razor,
but due to the protocol and the fact that Razor's server is not Free Software,
I decided to Pyzor should be based upon a new, lighter, more language-
independent protocol.
If you have an IMAP server with QUOTA Extension capability, you can use
this plugin to view the current quota usage (both size and message count),
which is displayed just above the folders list.
A warning message can also be displayed to users upon login if desired.
If no quota is set, nothing is displayed.
Twisted Words is the Chat and Instant Messaging portion of the Twisted
system. It is both a multiprotocol instant messaging client and server
and provides low-level protocol implementations of OSCAR (AIM and ICQ),
IRC, MSN, TOC (AIM) as well as Jabber libraries.
Twisted Words is available under the MIT Free Software licence.
Netmagis is a network management information system,
which allows a network administrator to:
- manage data for your BIND DNS and ISC DHCPD server,
- delegate DNS management,
- automatically generate network maps,
- assign VLAN to equipment interfaces via a Web interface,
- generate traffic graphs.
