History and use

A descendant of the original ARPANET delivermail application, Sendmail is a remarkably flexible program, supporting many kinds of mail transfer and delivery including the overwhelmingly popular SMTP. The original version of Sendmail was written by Eric Allman in the early 1980s at UC Berkeley, who had also written delivermail previously. Delivermail was shipped in 1979 with 4.0 and 4.1 BSD. Sendmail was shipped with BSD 4.1c in 1983 (the first BSD version to include TCP/IP).

Sendmail remains the most popular MTA on the Internet. Its popularity is due in part to its position as the standard MTA under most variants of the Unix operating system. According to one study, as of November 2001 approximately 42% of the publicly reachable mail servers on the Internet were running Sendmail.

Sendmail-8.12 as of September 2001 introduced support for Milter - external mail filtering programs/servers consulted during SMTP session.

Sendmail X

The next generation of Sendmail is called sendmail X (previously it was called sendmail 9). It is not an evolution of Sendmail version 8. Although it is purported to be a "complete new design", its design is in fact pretty much an exact copy of the design of Postfix (master becomes MCP, smtpd becomes SMTPS, local becomes LDA, smtp becomes SMTPC, trivial-rewrite becomes AR, and qmgr becomes QMGR). Some have speculated that this, in conjunction with the fact that Postfix exists and is in production use whereas Sendmail X is still being developed, has only accelerated the decline of Sendmail.

The first release of Sendmail X (smX-0.0.0.0) was made available on October 30 2005. The latest release is X-0.1.Beta1.0 and was released on February 4 2006.
