[Mailman-Users] mailman is receiving, but not forwarding emails.

[Kevin Nowaczyk]

I performed a massive debian update last week, which included a postfix update. Mailman may have updated too (it is currently 2.1.26). All other mail services on my server appear to still work (Drupal password resets, Roundcube webmail send/receive, virtual mailbox forwarding), but mailman is no longer sending out messages. The mailman archives are showing any messages that are sent to the list, but users are not receiving a copy. The mailman log files are suspiciously empty. The vet file does show where I tried to message a list I am not a member to, but nothing about the numerous times posting to a list that I am a member to, which is in the archive.
here is a typical log message:
