Sendmail is a computer program that is used to route email messages between computers. Sendmail is typically used on Unix-based systems, but it can also be used on other operating systems, such as Microsoft Windows.

Sendmail is a mail transfer agent (MTA) that implements the Simple Mail Transfer Protocol (SMTP). Sendmail is the most widely used MTA on the Internet. According to a survey conducted by Netcraft in 2006, Sendmail was used on over 67% of all Internet mail servers.

Sendmail is a complex program with a long history. The original version of Sendmail was written by Eric Allman in 1978 while he was a student at the University of California, Berkeley. Sendmail is now maintained by a team of developers at Sendmail, Inc.

Sendmail can be configured to work in a number of different ways. It can be used as a simple MTA that routes email messages between computers, or it can be configured to provide more advanced features, such as email filtering and virus scanning.

Sendmail is a free software program, and its source code is available under the terms of the GNU General Public License. Is sendmail still used?
