Sendmail experts - need help

[ThunderBalls]

I just recently installed a new version of Sendmail and I have a question about something. Everythings working, but when I send email to someone in the headers they receive it says:

Received: from saturn.domain.com (saturn.domain.com [127.0.0.1])
by saturn.domain.com (8.13.1/8.13.1) with ESMTP id k1M0kCQv002103
for <******@aol.com>; Tue, 21 Feb 2006 18:46:13 -0600
Received: (from domain@localhost)

So my question is what in the sendmail.cf file needs to be changed for it to put the actual IP instead of '127.0.0.1', and the actual domain instead of 'localhost'. Is it possibly a DNS issue? Anyone know?

I doubt that DNS is configured on the box that you're using and you will also likely want to build a virtualhosttable for domain names that you would like mapped to user accounts.

Without any other info, this is likely your best first line.
