As far as Mailman itself is concerned, it is not affected by any DNS
records. If the mail gets to Mailman, it will be processed the same
regardless of how it got there.

It is possible that there will be issues with mail delivery depending on
how Mailman delivers outgoing mail. This would depend on the MTA that it
is delivering to and what mail acceptance checks that MTA does.

This is not likely to be an issue if Mailman is delivering to an MTA on
localhost.
