If mailman is the only software running on that IP you can "safely" whitelist that IP and not every sender, at least you add it one time and that's it.
Also, just to be sure, please post output for:
cat /etc/hosts | grep localhost
And, can you try to change that "localhost" to "127.0.0.1" and restart mailman?
Thanks
Best regards
