I'm running sendmail and I've appeared on the CBL. I've already fixed a couple issues, but I can't figure out how to get rid of these last two localhost mentions. I commented out the localhost line in my /etc/hosts file and I made sure that there's a line in my sendmail.cf that reads:

Djmydomain.com

I'm going to keep looking for other things to do, but I'd really like my messages to not be flagged as spam because I'm a sendmail newbie. Thanks in advance!

Here are the message headers from an email I sent to my gmail account:

I just tried commenting out a few lines in /etc/hosts having to do with ipv6 and I got this:

Received: from mydomain.com (localhost [127.0.0.1] (may be forged))

I decided to uninstall sendmail and install postfix.

For some reason, uninstalling sendmail does not stop the MTA, so run

ps aux | grep mail

and kill the process manually. Postfix works great right out of the box.

edit:

Also, to prevent local delivery (unless you actually deliver email from the server using pop etc), in main.cf just get rid of the domain name reference. Works like a charm.

Another benefit of Postfix: mailq command shows bounces and replies from server if they deny the message. I could never figure this out with sendmail, but with postfix the mailq is very useful.

These look related to how you are connecting to sendmail (as in, opening a TCP/IP connection to it from the local machine). Do they look any different when you send mail through that sendmail instance from a different machine? If so, then your solution is to connect to the local machine differently when sending mail from itself.
