[NTLUG:Discuss] Comcast outbound email server

[brian@pongonova.net]

I echo Jay's comments about moving over to postfix.  Adding a new
forwarding record with post fix involves something like the following:

echo 'somedomain.com smtp:smtp.comcast.net:25' > /etc/postfix/transport
echo '.somedomain.com smtp:smtp.comcast.net:25' > /etc/postfix/transport
sudo /usr/local/sbin/postmap /etc/postfix/transport
sudo /usr/local/sbin/postfix reload

Easily scripted, you just add domains as needed. 

BTW, speaking of Comcast:  As of a few days ago, you can no longer
send mail to another comcast account without going through the
smtp.comcast.net gateway (IOW, the servers pointed to by Comcast's MX
records won't accept connections from Comcast-allocated IPs).  Which
means you'll need to add comcast.net to your transport file if you go
with postfix!
