  s/use/abuse/  ;-)  I question whether any mailbox with that many messages
in it can really be useful.  (As an active mailbox -- as an archive, yes.)

  The UW-IMAP server is really bad, period.  Rather like Sendmail, it
appears to be the popular implementation more by accident than anything
else.  And being popular does mean implementing something else is harder.

  Okay then.  I think that answers the question of why performance is not an
issue!  :-)

  I suspect we will have to do some real-world testing, and likely try more
than one solution, before we finally find what works best.  I've found it
damn hard to simulate mail usage accurately.
