I will not uncommonly 20 - 30 messages to a list within 10 minutes
(I often write several messages in parallel and then hit send on
them all more or less at once). For those on dialup accounts who
write their email while offline and then deliver next time they
dialin, I've regularly seen 50+ valid messages from a single user
within a 30 second period.
