remote users can't relay mail through my server.

I am tryingto configure Postfix to allow a remote client to relay mail.
I am using CENT OS 5 with Webmin/virtual min as my webbased admin tools.
The users are ably to pop/imap in and get their mail. I can send mail localy but not from a remote client like Outlook.

it is using postfix as my outgoing mail service.
When I added the domain I did so through Virtualmin.

Probably because they're trying to relay mail from an outside IP address. The only reliable way to do that is to set up authentication and allow relay based on the auth.

post your /etc/postfix/main.cf file.

Saslauthd is running? Did you restart postfix after making changes to the config?

You probably didn't set saslauthd to start on boot. Try manually starting it.

Will that cause pop3/imap to fail?

OK so it looks like it is SMTP remptly that is not listening anymore.

I can telnet to localhost smtp and it connects.

telnet localhost smtp
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).

Looks like my virtual interfaces for eth0 disapeared after I rebooted my system.
I created them through Webmin. Wonder why they disapeared after I rebooted?
