- * citmail.c v4.2
- * $Id$
- *
- * This program may be used as a local mail delivery agent, which will allow
- * all Citadel users to receive Internet e-mail.  To enable this functionality,
- * you must tell sendmail, smail, or whatever mailer you are using, that this
- * program is your local mail delivery agent.  This program is a direct
- * replacement for lmail, deliver, or whatever.
- *
- * Usage:
- *
- * citmail <recipient>       - Deliver a message
- * citmail -t <recipient>    - Address test mode (will not deliver)
- *
- */
+// This program attempts to act like a local MDA if you're using sendmail or
+// some other non-Citadel MTA.  It basically just contacts the Citadel LMTP
+// listener on a unix domain socket and transmits the message.  Really though,
+// if your MTA supports LMTP then you definitely should be using that instead.
