Hi Craig -- what Mailman version do you have on your system? You can determine that by logging in as root over SSH, and typing this command: rpm -qa | grep mailman

Hrm... something's definitely awry, as you certainly shouldn't get errors like that... but I'm not quite sure what the problem is :-)

Here's two other things to try --

  1. What do you get if you run: rpm --verify mailman

  2. What is the output of: rpm -qa | grep python

It looks like some of your Mailman files were changed since the package was originally installed.

Any idea what might have changed it? As those files shouldn't normally change.

However, my suggestion for fixing it would be to reinstall Mailman. You can do that by running this command:

yum reinstall mailman

That seems to have fixed it! I have no idea how those files could have changed - we haven't done anything w/ mailman on this server.... Thanks for the guidance! -- Craig
