Sendmail is a mail transfer agent (MTA) that is a well known project of the open source and Unix communities and is distributed both as free software and proprietary software.
Sendmail remains the most popular MTA on the Internet, although this is probably fading. 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.
