Thinking more upon this I think this was why we originally had the email
hostname set to the list server FQDN instead of our domain. originally mailman
lived on our mail server, but got moved to a different system when we moved to
Exchange for mail (and later on to O365) We had to create weird distribution
lists for all the lists ( ie: a DL t...@pharmacy.arizona.edu that has as it’s
only member t...@lists.pharmacy.arizona.edu ) for everything to work.
This worked well for years until we moved to a new mail spam and security
service and introduced stricter DMARC and DKIM settings for all our mail. This
is what broke one of our larger lists (our alumni outreach list, and of course
it’s Homecoming next week, and the last email resulted in 650+ bounces for
DMARC failures..mostly from aol and yahoo. )
Is it possible to have the email addresses of the mailman administrivia
addresses (-owner -bounces, etc) be the FQDN, but outgoing list traffic be set
to just the domain?
You could try this patch

And a similar patch to the get_site_email function in Mailman/Utils.py.
