It's kinda nasty, but required, as I've seen this problem before with

Here's an idea for plugin:
Check if the same message has already been received in the last n
hours
(a combination of message-id, sender and recipients should be
sufficient). If it is a duplicate, reject with an appropriate message
("550 You already sent me that message" or something like that).
Nice idea (procmail has something that does this) but unfortunately
that means the end user gets a 5xx error message.
