What is Postfix? It is Wietse Venema’s mail server. It was originally developed by IBM Research as an alternative to Sendmail. Wietse Venema continues to support Postfix at Google. Postfix works (or has worked) on AIX and BSD, HPUX, IRIX. LINUX. MacOS X. Solaris. Tru64 UNIX. It requires ANSI C and a POSIX.1 librarian. Postfix aims to be fast, simple to administer, and secure. Although the outside is very Sendmail-ish, the inside is entirely different. Multiple SMTP delivery over the same TLS encrypted connection. This reuses existing tlsproxy(8), scache(8) services. MySQL stored procedure support. Gradual degradation: In many cases, a Postfix daemon will log an error and continue to provide services that are still available instead of terminating with a fatality. Postfix can set an execute bit in a queue file. If this fails, no mail will be delivered.

EmailSuccess provides high volume email sending with enterprise-level SMTP Servers. EmailSuccess can be used as a Mail Transfer Agent (MTA) for all sizes of senders: ESPs and Marketing Automation Companies. High Performance EmailSuccess, an MTA, is designed to deliver large volumes of email. It gives the business full control over the Speed, Latency and Deliverability parameters. Deliverability Clients must be able to deliver their messages quickly. You must ensure that your email is not blocked by spam filters and lands in your inbox. Advanced Sending Intelligence Optimized delivery through automatic and real-time tuning of email delivery parameters; platform tuning is made easy.

The Sentrion platform for sending mail is designed to handle large, complex environments. However, we make a portion of it open-source. Sentrion isn't for everyone. However, if you use open-source email in a complex environment and need an enterprise platform to support your messaging roadmap for years (virtualization of consolidation, cloud migration, etc.) Sentrion may be right for you. The Domain Keys Identified Mail Internet standard allows email senders to digitally sign messages so that recipients can verify that they have not been forged. DKIM sender authentication scheme lets the recipient of a message confirm that the message was sent from the sender's domain. It also ensures that the message content is not altered. DKIM, a cryptography-based solution, provides businesses with an industry-standard way to reduce email fraud and protect their brand and reputation at a relatively low cost.

Exim is a mail-transfer agent (MTA), which can be used in Unixllike operating system. Philip Hazel wrote the first version in 1995 for the University of Cambridge Computing Service's email systems. Exim is available under the GPL and is free to download and modify. Exim is somewhat similar to Smail 3. However, it has diverged from it and now exceeds it in ease-of-use and flexibility. Both follow the Sendmail design model, where one main binary controls all facilities of the MTA. Some consider this monolithic design to be less secure and slower. However, Exim's security record and speed are better than Sendmail. It excels in advanced areas like address routing, queue handling, and testing. Exim does not have a Graphical User Interface (GUI), but some Linux distributions do.
