[Mailman-Users] Not able to send messages to lists I've setup

[Jody Cleveland]

Hello,

I've got the latest version of Mailman running on a redhat 3.0as server.
When mail comes in, the redhat handles it with MailScanner coupled with
spamassassin and f-prot. Then, that machine forwards it on to our
exchange 5.5 machine.

I've got mailman running fine. It installed ok, I can create lists using
the command line, and the web site. I can also subscribe to lists using
the website. The problem comes in when I try to post messages to the
list I subscribe to. I get a Undeliverable message from the exchange
System Administrator:

	The MTS-ID of the original message is: c=US;a= ;p=Winnefox
Library;l=MAIL-041201174732Z-13761

I guess I don't understand why exchange is taking issue with this. I can
send email to my user account on that linux machine, and it works fine.
Is there a setting somewhere I need to change?
