I'm looking to replace antique SmartList mail list processing software with something more modern and capable. The main thing that makes this necessary, aside from the fact that there has been no active development on either SmartList or Procmail upon which it relies for more than a decade, is the fact that it does not re-write sender addresses and does not deal with SPF, DKIM, and DMARC, so has become unreliable at delivery, depending upon whether the senders sites sign their e-mails with one or more of these and the receiving sites check.

Capabilities I need, the ability to re-write and hide the sender addresses, the ability to deal with SPF, DKIM, and DMARC in some sane way. If the addresses are re-written and any originating SPF, DKIM, and DMARC signatures removed this should not be an issues. A web archive of some sort for each list. A web administrative function for list owners. The ability to install on a Ubuntu 22.04 platform, and be totally open source.

I originally looked at Mailman, but it requires Python 2.7 which is deprecated, exactly what I'm trying to get away from. Then I looked at Mailman3, aside from being a real clusterfuck split up into separate bits, it also lacks usable documentation and seems wired to Ngnix and I use Apache2.

So looking for other recommendations.
