There have been a few posts about this sort of thing. The approach
you're using, does appear to be a slightly "novel" approach to this,
and not one *I* would deploy, for a variety of reasons.

Indeed.

example.(com|net|org), q.v. RFC 2606 (unless, of course, you mean
'server.com').

That's one of the bits that fills me with dread (for a variety of
reasons), assuming I'm not missing something, and my reading that as
    ...
                IN      MX  0   exchange
                IN      MX  10  mailman

    (in standard zonefile notation)
is correct.

FWIW, my approach in the past has always been to set-up Mailman as
lists.example.org, and then use genaliases, awk/sed/perl, and a text
file to forward 'domain' mail to 'list mail'.

e.g., were <list-example at lists.example.org> to exist (as a list), at
the Exchange end, I'd forward <list-example at example.org> to
<list-example at lists.example.org>, along with the various suffices.

I did once work a way to script this (at Exchange) -- it involved a
CSV file -- so it's not too difficult/cumbersome -- although a bit of
a nuisance when adding new lists: it's something else to do.

This also assumes that typing "lists." is too much effort for your
users, or that maintaining a (lists) GAL is not something you want to
do.
