+relays.  It's useful for systems such as Web servers that must be able to send
+email notifications, without having to run a full-blown MTA such as sendmail
+or qmail.
+
+Nullmailer is designed to be simple to configure, easy to extend, and secure.
+It requires little ongoing administration.  The included @command{sendmail}
+emulator front-end should allow most (if not all) sendmail-compatible programs
+to run without any changes.")
