[Mailman-Users] DKIM, SPF, DMARC, Mail_as_list all working, but MUAs not happy

I am using a very old version of mailman, 2.1.16.  I wanted to update to a
newer version during this migration, but I was too concerned that I would
break something in this complex server by upgrading and changing the
dependencies that new versions of mailman require.

A large number of our users are not happy with how mail is presented when
Mail_as_list is active.  They messages appear as attachments in some MUAs.

If I change from Mail_as_list to Mung From, DKIM does not validate.

I noticed from previous emails I received from this list that DKIM does not
validate here either.

Can I just switch the list to Mung From with some certainty that the email
providers will continue to relay our traffic as we have valid SPF and DMARC

Would switching to a later version of mailman make this any better (and

Thanks in advance,
