I cannot believe that ext3 chokes on just 3000 directory entries in such 
situation. I would think that one would notice the same with 20,000 
messages per mailbox.

How about really use another mail client for testing, as Marcus suggested, 
e.g. some brain-dead MUA, that does not try to be smart, for example 
Alpine or Mutt :)

Also, try to log the session, maybe the user watches all 3000 folders for 
changes. So they all will be selected in a (short?) period of time again 
and again. Maybe a firewall in between is casuing a throttle, because of 
too many connections or something?
