Yes it's a sendmail configuration and it has actually been reconfigured
completely as the new domain with an alias for the old domain, so if users
are receiving mail to either address it ends up in the same mailbox.
Rewriting in the MTA is definitely something I had not thought of, but your
two-liner looks much easier ;-)  Rule #1 in configuring sendmail... if it's
working don't touch it :-)

That's it, that's the one :-)  Basically all of the user memberships will be
converted for the new domain, and we just don't want posts to get held for
the people who are 'less than prompt' in reconfiguring their email clients
during the transition.

Will give this a try and see how it goes :-)
