[Dovecot] dovecot-1.0-beta3 in production

[Branko F. Gračnar]

Hello there!

I've migrated our courier-imap production imap/pop server to dovecot 1.0-beta 
few days ago. In general dovecot performs excellent, but i've encountered 
several "bugs" in dovecot log:

I have multi-domain setup with several hundred users, emails are delivered 
using dovecot-deliver LDA, dovecot indexes are outside mailboxes, indexes and 
mailboxes are on local filesystem (xfs). I'm using linux 2.6 on slackware 
platform.

If you need any more info, just let me know.

Best regards, Brane
