How can I enable/force compression?

It looks like; but then imagine me asking this question on an Outlook
mailing list:

"Hi, I have a Cyrus mail server running on Linux and..." :-]

Anyway, Ken's suggestion with UIDVALIDITY it's a good start for me.

Oh, tell me there is a patch to do this. Because last time when I checked:

"As in earlier versions of Outlook, Internet Message Access Protocol Version
4rev1 (IMAP4) accounts and HTTP accounts use .pst files that do not use the
Unicode format. Therefore, the .pst files for IMAP accounts or for HTTP
accounts are limited to 2 GB."

Already got there with one of my users... :-s


PS(/2) Nobody seems to answer to the other one though: Outlook idiocy aside,
is there a way to enable compression "on the fly"?
