Do you actually have the alias for testl...@example.com in either of your aliases files (most probably should be /usr/local/mailman/data/aliases)? The only way postfix will know what to do with that address is via an alias directing it to call a MM function that posts the message to the list. Despite my better judgement, I’m still on v2 & such an entry looks like:
testlist: “|/path_to_mailman/mail/mailman post testlist” Been *many* years, but IIRC the docs note how to set those up properly & it was a manual process (but once you have the set for one list, copy/pasta + a little search/replace will get you the rest). -Guy > On 2025 May 12, at 10:08, Sean McBride <s...@rogue-research.com> wrote: > > Hi all, > > So I have/had a working postfix+dovecot setup, and then I installed mailman2. > > It largely works.
