UnderSMTPD, the underscore SMTP daemon

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.

UnderSMTP was originally written to be used with the Request Tracker ticketing system.

UnderSMTP uses Net::Server::Mail to do all the hard work.
