When I attempt to send a post to mailman, my GroupWise (8) GWIA sends me an e-mail that completion of the e-mail has been delayed because the server (Linux) is down, which it isn't. This message repeats about every fifteen minutes or so.

Hum. This makes me believe that GWIA is not able to route email to the MTA, Postfix (guessing based on previous post), running on the Linux host.

What (sub)domain are you using for your Mailman mailing lists? I.e. are your mailing lists part of your ccs135.com domain as in mailing_l...@ccs135.com or are they part of a sub-domain as in mailing_l...@sub_domain.ccs135.com?

If you are using a sub-domain, do you have GWIA configured to route said sub domain to your Linux host?

Since I've not worked with a Linux mail server before, what is the procedure, what software do I need, to send and receive e-mail using the Linux server as a regular user just to make sure mail is coming and going or to see where it might be hanging up? For install, will Thunderbird work, and, if so, how does it need to be configured? I realize this is very elementary, but it isn't cooperating like Novell's GroupWise or Microsoft's Exchange server.

To start with, make sure that root on the Linux host can send it's self mail. I typically do something like

   'ls' | mail -s "Testing..." root

Note the single quotes around ls to turn off all formatting that may mess with the email.

If that does work, try the same type of thing but sending the email to an address on the box with the full domain name on it. I.e.

   'ls' | mail -s "Testing..." r...@example.net

If that works, try sending the email to somewhere non local to the system.

These all check "sending" of email, thus testing to make sure that your MTA is installed, functional, and running. If the above tests pass, then your problem likely is with routing email back in to the system.

If you can, please give more details about your install as they will help in further diagnosing what is going on.
