That one does sound a bit fishy. Are the index files even compatible to 
each other?

Other than that, a little bit of info:
- Dovecot running on two different servers, providing IMAP and POP3 
(both with and without SSL)
- Storage format is maildir
- MTA is sendmail, MDA is a custom bit of software doing funky stuff 
like MySQL DB integration, autoresponders, spam/virusscan and so on and 
so forth
- LDA is dovecots delivery agent, plopping mails pre-sorted into various 
- One server has about 50 users out of which 15 use IMAP, the rest uses 
POP3, the other server has about 10 IMAP-only users.
- Mail quota is set to 5GByte for both servers
- Clients use Outlook/Outlook Express/Thunderbird - the latter with 
check_quota plugin

Biggest single folder size is around 1.5GByte, no idea how many mails. 
Average access time to that folder from Thunderbird is about 15 seconds 
or so for initial loading, pretty much instant when opening any mail in 
there. Indexing it from scratch takes quite a bit longer though, about 7 

Hope that helps
