[Mailman-Developers] Repeating messages

[Nick Arnett]

FYI, Listserv prevents duplicate messages by checksumming every message and
rejecting those that appear to be identical within N minutes... in case
nobody has ever suggested that feature.

And as long as we're on that subject, they also stop some spam by sharing
the message data and temporarily (24 hours, IIRC) blocking any address that
sends the same message to N mail servers around the same time.
