Mm-handler works well when mail-lists are in a separate domain.
I ran across postfix-to-mailman.py while researching mailman to postfix
connections. I realized it performs the same function as mm-handler. I
changed mm-handler to be a drop in as a replacement for
It is under:
I did a test install of mailman with Postfix to test it. It worked.
I also setup a Mailman to Postfix connection using the aliases method as
described in the documentation. That worked fine also. I don't use
Postfix but using the postfix-to-mailman.py seemed a little more obvious
than setting up through the aliases method. The Postfix package on
CentOS 7 even had comments where the mailman transport entry would go.
Configuring is especially tough if you are not familiar with Python. :-)
Setting up mailing lists in a separate domain has a nice administrative
appeal. I did a little more research to see how popular that method
might be. I got a list of 1922 US universities and 457 have a host
"lists...." and 191 have a host "list..." in their DNS. I surveyed a
few and ran across: Mailman, Lyris, Sympa, Listserv, Majordomo, and
Google groups. Many universities outsource their Email to Outlook which
has it own Group capability.
Running mail list software is clearly popular. Both mm-handler and
postfix-to-mailman.py are contributed code. The folks who package the
various tools add glue to make them easy to use. It looks like both
Sympa <https://sympa-community.github.io/manual/>and Mailman have very
similar requirements. Maybe time to work together?
I can hook up any mail system. Just give me the list of mail-lists and
tell me how to inject messages. Glue will be more specific to a Mailer
and OS than either Mailman or Sympa. I think we get a benefit if we
make a clean interface between Mailman and its feeding MTA. We can then
eliminate some of the hacks like mm-handler.
I have some ideas for Mailman2. I'll follow up.
