smtpd

smtpd is a Simple Mail Transfer Protocol (SMTP) daemon which can be used as a machine's primary mail system. smtpd can listen on a network interface and handle SMTP transactions; it can also be fed messages through the standard sendmail interface. It can relay messages through remote mail transfer agents or store them locally using either the mbox or maildir format. This implementation supports SMTP as defined by RFC 5321 as well as several extensions. A running smtpd can be controlled through smtpctl.
