[Mailman-Users] Postfix delivers to mailman, but not aliases

Hi list,

I recently migrated our mailman server from an old SLES 11 box to Ubuntu 16.04.3 LTS, and installed Mailman from the Ubuntu repositories along with Postfix and other prerequisites. Mailman itself is working fine, but I have a handful of regular email aliases in /etc/aliases which do not receive mail, and when examining the logs, get bounced with a “User unknown” error. What did I screw up?

(I’ve checked my aliases and they’re good, and I’ve run the newaliases command numerous times).
