This shouldn't really be happening. They're gone only if client issues
EXPUNGE command in the .EXPUNGED/INBOX mailbox. Is your Outlook really
doing that? (If so, I guess it opens all mailboxes and issues EXPUNGE
for them?.. And I guess you've also made .EXPUNGED/ visible to clients?)

Yes, this is probably a good idea in any case. Done:
http://hg.dovecot.org/dovecot-1.2/rev/45b110c8da62

Still I'd like to know what exactly was happening with you before, just
in case there's something else wrong in Dovecot.
