postfix - Straight from http://www.postfix.org/: What is Postfix? It is Wietse Venema's mail server that started life at IBM research as an alternative to the widely-used Sendmail program. In other words, better than sendmail. I still can't remember why I have a bad taste in my mouth from sendmail. To use the transport map, dont' forget to add transport_maps = hash:/etc/postfix/transport to the main.cf file. Remember, kids: 1) update transport; 2) postmap transport; 3) postfix reload.
