Let's call the host's primary DNS entry "uglyhostname" and we'll call the desired hostname alias for mailman "lists".
And you set up "lists" to be a CNAME alias record pointing to "uglyhostname", right? Well, don't do that.
Make sure that "lists" resolves directly to the correct IP address, and that the reverse DNS for that IP address also points back to "lists" as well as "uglyhostname".
Search the archives for "CNAME" if you need more details as to why this is the case. There might also be a FAQ Wizard entry on this subject.
