BackupMX consists of two programs, 'Store' and 'Forward'. Store accepts SMTP connections, takes all mail given to it, and stores it in a file. Forward takes that file and forwards it over SMTP to a fixed destination. This is code for integrating into your own projects rather than using as is. It is suitable for creating a disaster-recovery mail handler, but would also make a good basis for a spam filter, a tarpit, a honeypot, or a greylist filter. It is written in simple C, and has no external dependencies such as libsmtp.
Dkfilter is a DomainKeys implementation for the Postfix mail transfer agent. It is implemented as two filters (or SMTP proxies). There is an "outbound" filter for adding DomainKeys signatures to outgoing email and an "inbound" filter for verifying signatures of incoming email. The filters can be plugged into Postfix as either Before-Queue or After-Queue Postfix content filters. For more information about DomainKeys, see http://antispam.yahoo.com/domainkeys.
femail provides a sendmail-compatible commandline interface and forwards mail via SMTP. Unlike many other implementations, it is fully RFC 2821 and 2822 compatible. It embeds extra environment information from Apache in the header, if present, to help with tracking down abuse. It is written with security as a main design goal.
PigeonDeliver is the delivery agent of the PigeonAir project, a solution to easily build up clustered, scalable, and modular email services. PigeonDeliver is modular in nature, allowing it to be used on Postfix and other MTAs using their own native APIs without performance loss. It allows mail services to be easily and transparently distributed among a cluster of mail server, easily supporting new services and new modules added using the PigeonDeliver API, which simplifies writing filters and/or delivery agents.
dkimproxy is an SMTP proxy that signs and/or verifies Domain Keys Identified Mail (DKIM). It is designed to work with Postfix. It comprises two separate proxies: an "outbound" proxy for signing outgoing email, and an "inbound" proxy for verifying signatures of incoming email. With Postfix, the proxies can operate as either Before-Queue or After-Queue content filters.
Open5066 is an implementation of the NATO NC3A STANAG 5066 protocol stack for HF radio communications. It aims to implement all of SIS (Annex A), DTS (Annex C), and some of the application layer (Annex F) functionality such as HMTP. The concrete embodiment of Open5066 is the s5066d daemon.
Insight Server is a Linux-based email server utilizing open source components to provide a highly reliable, scalable, and cost effective email solution for customers of all sizes. It's designed to facilitate complete messaging and collaboration capabilities within a company. It supports all standard protocols, and provides backup and recovery tools, server redundancy, migration tools, and resource management.
libspawner implements the MTA side of Sendmail's Milter (mail filter) protocol that is used by the MTA to delegate policy decisions to external daemons. The main purpose of this library is to enable other MTAs, or any mail-handling software, to talk to the existing mail filters that have been developed for Sendmail.
