If you're going to accept mail for a list through several alias posting addresses, you should bloody well filter the incoming mail for duplicate message IDs. Sending out two copies of every mail because someone in upthread somehow sent to one address and also CCed the other is, at best, clumsy.
And if you can't do it right, make up your mind and don't accept mail on two addresses. Regards, -- Aristotle Pagaltzis // <http://plasmasturm.org/>
