Server :: Setting Up Sendmail On A Blank RHEL 5.5 Server Setup

Having some issues setting up sendmail on a (basically) blank RHEL 5.5 server setup. My ultimate goal is to be able to automagically send logs / errors / notifications to ourselves from the server.

Our basic setup is a Win 2003 domain with exchange running on mail.domain.com.au.

I've edited the '/etc/mail/sendmail.mc' and added the :

Code:

line to it.

Also added the domain (domain.com.au) to the '/etc/mail/local-host-names' files

Also edited submit.mc and added

Code:

When I try and send a mail from root or a test user to one of the domain accounts, it seems to go fine, i.e no errors are reported but it never gets delivered.

From the mail logs:

Code:

So it seems to be sent to the queue no problems and when I check the queue :

Code:

Total requests: 0

Not nothing ever gets received. Am I missing something? I have read and read and read but dont seem to be getting any furthur.

So in the end this server doesn't need to do anything except be able to send mail from root to an external mail address.
