Sentinel is a sendmail milter API implementation. This package might
be usefull for Unix system administrators who is using freeware
Sendmail. May be it's one more milter, but on the other side it's
flexible enough to satisfy more or less subtle requirements for mail
filtering.
open source implementation of the Sender ID specification as defined
by the Internet Engineering Task Force's (IETF) MARID Working Group
(Mail Authorization Records in DNS).
sid-milter implements the -core and -protocol specifications.
Additionally, sid-milter implements the "SPF Classic" record protocol
(v=spf1) as defined by the SPF community.
iXhash is a plugin for the popular spam filter SpamAssassin.
It computes MD5 checksums of fragments of the body of an e-mail and compares
them to those of know spam. As such it works similar to the now standard
plugins that use the Pyzor, Razor and DCC software packages from within
SpamAssassin.
Modern user interface.
Complete support of IMAP and SMTP protocols including SSL and STARTTLS.
Minimalistic resources requirements.
Direct access to mail server is used (mails are not stored locally
on web server).
Allows for adding multiple accounts to primary one, simultaneous
access to different accounts in different browser tabs is supported.
Additional identities.
Administrative panel for configuring main options...
Virtual Exim is a PHP and SQL based approach to hosting multiple email domains
using Exim. Exim is used to collect mail for local users, and an SQL backend is
used as a data store for users passwords, and other configuration information.
wmbiff is a dock app that displays the total number of messages or the
number of unread messages in different mailboxes. It supports up to 5
mailboxes. It is also possible to execute user-defined commands on new
mail arrival (for example, play a .wav file).
The Gnome Gmail Notifier project aims to provide a stable, efficient
GTK+2.0 application that provides periodic updates that pertain to the
user's gmail inbox.
The Notifier presents itself as a system tray icon in the GNOME2
desktop, displaying a small balloon popup when the user recieves new
mail.
RFC2822 introduces a slightly different format of date than that used by
RFC822. The main correction is that the format is more limited, and thus easier
to parse.
Courier-IMAP is a server that provides IMAP access to Maildir mailboxes.
This IMAP server does NOT handle traditional mailbox files
(/var/spool/mail, and derivatives), it was written for the specific
purpose of providing IMAP access to Maildirs.
Courier-IMAP implements some extensions to the basic Maildir mail
storage format in order to support some additional features, such as
folders and "soft" quotas. This is done in a way that's backwards
compatible with the standard Maildir users (although, of course, they
will ignore the additional features). Other software that understands
and uses the same Maildir extensions is SqWebMail, and maildrop.
Features:
* Extremely small footprint.
* Abstract authentication modules.
* Virtual mailbox support.
* Pop3 daemon.
Qpsmtpd started as a replacement daemon for the SMTP receiver (qmail-smtpd)
from the qmail mail transport agent (MTA). qmail-smtpd has a number of
shortcomings (e.g. being unable to check the validity of a recipient mail
address) and is written in C which makes it burdensome to modify and extend.
Qpsmtpd, on the other hand, is written in pure perl and can be customized
easily. It consists of a core that implements a complete SMTP server, and a
number of plugins/modules which control the operations. Such plugins
include plugins to check the recipient and sender as well as plugins for
virus scanning, spam checking, blocking lists (dns and rhs), AUTH and TLS.
Qpsmtpd can not only be used with qmail but also with e.g. postfix and
exim. It can also write messages to a Maildir or forward it to a remote
host without buffering.
