Sounds reasonable. Mind you, it feels scary migrating our 20,000 users 
to an "alpha" product! (This week I managed to switch ~120 University 
Admin staff, who are some of our heaviest users, to use Dovecot 
1.0-stable with mbox, instead of UW-IMAP, without them noticing! So far, 
it seems that Dovecot is reading one third of the disk blocks and using 
half the CPU than UW-IMAP, for them.)

I'm still not convinced the cache file is shrinking properly for me. Do 
entries get expired after a set time at the moment (in 1.0-stable)? 
Anyway, it would be nice to be able to configure the lifetime (e.g. may 
be less than a month). I've noticed that if you've got a lot of messages 
- and I'm being deliberately naughty with my INBOX ;) - doing a full 
search will lead to a big cache file, even though the user is less 
likely to read the oldest messages.

Best Wishes,
Chris
