Troubleshooting Mailman

check again for TYPOS mistakes.

If spam headers (X-Spam) are not present in the incoming emails, make sure that your domain is in local_domains_acl list, which is in /etc/amavis/amavisd.conf file.

If you're having problems with Amavis and not sure where to start, here's a clue - instead of starting amavis the usual ay (/etc/init.d/amavis start), type this instead: */usr/sbin/amavisd-new debug*

Then if you trying sending an email through it, you'l be able to see the details, how it processed that email, and therefore hopefully you'll be able to spot anything that went wrong.
