First of all, my .02 on rebooting - If you do a yum upgrade that
updates "system files", you should reboot. If you don't, and there is
some issue due to the upgrade, the next time you have an unplanned
reboot due to a power failure or some other external event, you will
have problems ultimately caused by this upgrade, and you may not even
remember this upgrade as a potential cause.

Regarding the Mailman issue per se, was Python involved in the upgrade?

See various Mailman logs such as error and smtp-failure for problems.
