Postfix

Postfix is Wietse Venema's mailer that started life as an alternative to the widely-used Sendmail program. Postfix attempts to be fast, easy to administer, and secure, while at the same time being sendmail compatible enough to not upset existing users. Thus, the outside has a sendmail-ish flavor, but the inside is completely different.

Dovecot

Dovecot is an open source IMAP and POP3 server for Linux/UNIX-like systems, written with security primarily in mind.

Cyrus IMAP

The Cyrus IMAP server differs from other IMAP server implementations in that it is generally intended to be run on sealed servers, where normal users are not permitted to log in. The mailbox database is stored in parts of the filesystem that are private to the Cyrus IMAP system. All user access to ... [More] mail is through the IMAP, POP3, or KPOP protocols. The private mailbox database design gives the server large advantages in efficiency, scalability, and administratability. Multiple concurrent read/write connections to the same mailbox are permitted. The server supports access control lists on mailboxes and storage quotas on mailbox hierarchies. [Less]

DBMail

Fast and scalable email services based on storage of messages in a database. Robust support for IMAP4r1, POP3, LMTP, MANAGESIEVE. Fully normalised decomposition of messages into headers and mimeparts. Mimeparts are stored in a single-instance paradigm, preventing unnecessary duplication. ... [More] Also supports a scalable connection pool to limit the database connection load under high concurrencies. [Less]

mailx

Heirloom mailx (previously known as nail) is a mail user agent (MUA) for Unix systems. Highlights are: * Derived from Berkeley Mail 8.1. An interface like the original Berkeley one is still optionally available. * Is a free implementation of the System V mailx command and features an interface like that by default.

Openwall - popa3d

popa3d is a tiny POP3 daemon for Unix-like operating systems. It was designed with security as the primary goal. popa3d has been integrated into OpenBSD base tree. It is the default POP3 server on Openwall GNU/*/Linux (Owl), recent versions of Slackware, and distributions by ALT Linux team. ... [More] popa3d is also a part of Debian GNU/Linux, Gentoo Linux, and ASPLinux. [Less]

pfixtools

A collection of Postfix-related tools, including a SRSD daemon and a policy daemon. "pfix-srsd", our first tool, is a tcptable lookup service for Postfix which performs SRS encoding and decoding. The second tool is "postlicyd", a policy daemon for Postfix with a very ... [More] flexible configuration. It can be used as a replacement for whitelister and postgrey. Postlicyd is able to access R(H)BL databases by DNS or by directly reading rbldns zone files. [Less]

Archiveopteryx

Archiveopteryx is a mail server system optimised for long-term storage and heavy access. It comprises a set of server programs that provide access to mail stored in a relational database (PostgreSQL). It runs on Linux, FreeBSD, NetBSD, OpenBSD and Mac OS X.

Veldfire

Veldfire is a frontend to the Riverdrums C library, and is aimed at simplifying email functionality. The project provides interfaces to sending email, attaching files and sending mail to lists.
