+This is a minimal SMTP server which only forwards mail to pipe destinations +in /etc/aliases. It does nothing else. Its intended function is on an +internal mail server that forwards mail to other programs on a per address +basis.
+UnderSMTPD reads /etc/aliases for usernames; if a match is identified +the message is piped to the given program. Any problems executing the program +will cause a temporary SMTP error to be returned to the connecting client.
+Other kinds of aliases are not recognized and cause a perminant SMTP error +to be returned to the connecting client, as do usernames not found in +/etc/aliases
+UnderSMTP was originally written to be used with the Request Tracker ticketing +system.
+UnderSMTP uses Net::SMTP::Mail to do all the hard work.
