SMTP is SMTP whether spoken by MUA or MTA. All mail servers have "smart relay"
or "relayhost" functionality. in postfix, put in main.cf
relayhost=smtp.east.cox.net

You will also need to use virtualhosting features and set your mail server
name to whatever your IP reverse DNS lookup is. Again in postfix main.cf
myhostname = ipmy-ip-add-ress.no.no.cox.net

And then I set up virtual hosting for my LAN

Probably not necessary since you're relaying through Cox but if you want
to talk to some mail servers, you need to set up MX records in DNS AND have
forward lookup = reverse lookup (AOL does this).
