a twist on this: we have an external researcher who can't send e-mail
to our users since all his messages contain
Message-ID:
yes, a blank ID. we don't reject this, but when it reaches Cyrus, it
will do duplication elimination based on the (msgid, folder) tuple, so
any subsequent messages are silently dropped.
I think it would be better if we rejected such e-mail messages, but I
haven't had time to update the configuration yet.
