Many of our lists have full addresses in the form of 'foo-bar(a)baz.org',
with corresponding alias names 'bar(a)baz.org'.
When someone sends a message To:foo-bar@baz.org and also Cc:bar@baz.org,
his or her MUA sends two separate messages to the list which transmits
these duplicates to list members. However, only one copy makes it to
the pipermail HTML archives.
Is there a Mailman way to activate, in the context of delivery, the same
duplicate suppression that occurs when archiving? If not, I will have
to do this based on Message-IDs on input at the MTA, but I would prefer
to do it via the mailing list manager if this is already possible.
Thanks,
