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(8) 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(8).
The options are as follows:
-D
macro=value-d
