Ya think? :-)

This has been done.  Note that the way this particular instance took 
place was a user had a weak or leaked password, so the spammer came in 
through our webmail gateway.  Flow control won't work on that machine, 
as it services hundreds of users.  Neither will IP based restrictions.  
The only think I can think of that would have caught this would have 
been measuring the volume-- they're forced to use their own email 
address, so after the first dozen messages, I'd have loved for something 
to have said "Wait a damned second here..."
