Sendmail is an SMTP-compatible mail server that has been used for over 20 years in the UNIX and Internet environments. It is an MTA (message transfer agent) that transfers messages from user agents and delivers them to mail servers. Like other MTAs, it attempts to deliver mail to the recipient immediately; but if the recipient's mailbox is not available, it queues the message for later delivery.

Historically, Sendmail has been hard to administer and has had a number of security problems. But many of Sendmail's problems have been worked out. Sendmail, Inc., has a commercial version of the package with many enhancements. You can also obtain Sendmail source code from Sendmail.ORG.
