I have worked with commercial packages that you could do that with.  They
cost in excess of $50K.  They have the user list stored in a database common
to all lists in the partition (a partition being something that limits the
visibility of the databases).  The particular package was UnityMail, however
it is a monster to administer and I would sooner gnaw off my right arm that
to suggest that someone use it.

Basically, you can't. This is something that can only be fixed on the
client side.

think about it -- four pieces of email are being sent to four
addresses, which all happen to end up in the guy's mailbox. But once
they leave the sender's client, they're completely independent of
each other, being sent to independent addresses (that happen to all
go through the list server, but at different times). There's really
no way for a list server to carry state to deal with something like
this, and arguably, it shouldn't even fi it could.

the guy's mail client can do something about it, by recognizing
duplicate Message-IDs or some other way of tracking duplicate
messages, but it's in the hand of his client, not the sender or the
list server.
