I installed mailman (again) and I set up the mailman mailing list and it says it will send the list owner a notification that the list was created. I never receive the notification. I go into the mailman logs and in the smtp-failures log it says that an email from mailman-bounce was denied with a User Unknown error. The /usr/share/mailman-2.1.4/INSTALL.REDHAT says that this error can happen if the mailman list is not properly set up in /etc/aliases, but it was properly set up in /etc/aliases because I never deleted it from the previous installation. I've run newaliases and tried setting up the mailman list again (after removing it, of course) I've tried restarting the mailman service and creating other lists and I cannot get past this error. Pleas help!
