That's not going to go away.  We have ARC support in Mailman 3, but
(a) like most envelope manipulation, that should be done in boundary
MTAs, not in Mailman, and (b) ARC implementation is not universal.
*Very likely* some of your subscribers are going to lose mail if you
depend on ARC, rather than munge from.

I sympathize.  I tell the little kids I meet that my hair grows out of
the bottom of my face, not the top (it's very alliterative in
Japanese[1], the kids frequently don't get it but the accompanying adults
usually laugh).

The obvious "turn-key" installation is to use the Docker containers,
which Abhilash keeps fairly up-to-date.  But see comment below about
universal working solutions.

Which distro do you have?  Are you using the distro's packages of
Mailman 3 (not yet a good idea, unfortunately), or installing from

It's email.  There are no universal working solutions.

Who is this guy and has he consulted us?  I'd like to do an archive
search if he's done so to see what the issues are.

What's iRedMail?  How does it fit into the community your lists serve?

Works for us, for values of us including python.org.

mailman-users at mailman3.org is the Mailman 3 version of this list.  If
your friend is the type to get his hands dirty with code, and has the
time for development activity, mailman-developers at python.org would
also be useful.

You might be better off getting bids from consultants.  There's a page
listing them on wiki.list.org.

 > I have looked for both free and commercial alternatives to MM,

There are sites that support MM commercially.  I think the prices are
reasonable, of course YMMV on that.  Again, there's a page for those
services on wiki.list.org.
