162 duplicate messages, as of 2:04 PM PST today, to be precise. This
same thing happened when I was on the Exchange team at Microsoft, but
that was on a pre-release dogfood mail server, not even a beta for a
pre-release. Good thing it was only in-house Microsofties who had to
field the thousands of garbage messages when that happened.
The problem then was that they had to flush the mail queue that had
become clogged up with duplicate messages because some bit of code had
looped back on itself.
Granted, the list mail server probably isn't an enterprise version, with
mail replicating between hundreds of servers, but as Chris mentioned, it
does take a feed from the newsgroup, and there's plenty of room for that
to break. Quite likely the fix for any mail server whose mail queue has
been corrupted is to flush it.
