General :: Webmin: Postfix Relayhost With ISP RoadRunner?

From the posts relevant to postfix I could not find the particular combination of issues I'm facing. Any pointers or references to posts will be greatly helpful. I have CentOS server running Postfix which was recently moved into my house running over TW cable (Austin RoadRunner). In Webmin -> Postfix Mail Server -> General Options - Other General Options - 'Send outgoing mail via host' (which is the relayhost) is set to:

Code:

[URL]

I expected the relay to reflect this in the log but it doesn't When I send an email I see this in /var/log/maillog

Code:

Jul 21 17:10:46 cromagnon sendmail[14853]: p6LMAjlu014853: from=root, size=49, class=0, nrcpts=1, msgid=<201107212210.p6LMAjlu014853@cromagnon.com>, relay=root@localhost

And a timeout occurs a little while later

Code:

Jul 21 17:17:04 cromagnon sendmail[14853]: p6LMAjlu014853: to=ravi@pobox.com, ctladdr=root (0/0), delay=00:06:19, xdelay=00:06:18, mailer=relay, pri=30049, relay=[127.0.0.1] [127.0.0.1], dsn=4.0.0, stat=Deferred: Connection timed out with [127.0.0.1] I basically *all* mail from all domains on this server to go through the relayhost. I understand there are a million caveats but I wish someone could help me with the basics.

BTW I've also tried to set the relayhost to

Code:

[URL]

however the log still shows . . .relay=root@localhost . .
