Hi Rien,
I figured out what I was doing wrong! I reinstalled Mailman (rpm -Uvh *.rpm --force). I also had email blocking turned on through one of the contribs I had installed. Once I added in my mailing list address to allow, and addded in maillist-*@domain.com also, so the -request and -help addresses could get through, it as all OK.
However, I had to manually edit both the files you mentioned above for my domain name and then reboot.
Now I have a few follow up questions:
* How do I update Mailman to the latest version? Just download and install the Mailman 2.1.6 rpm?
* How do make it so that Mailman can do mailing lists for the other domain hosted on this server? What is the syntax for adding in second domains to those files?
* How do I delete the existing Mailman list? I don't want this one, and won't use it? Can I simply manually delete it from the lists folder?
