[Dovecot] Problem with indexes

[crs]

Hello.

Dovecot is really good software but I have one big problem with indexes. 
I have server with a lot of mailboxes - filesystem has quota enabled and 
I can't resign it from different reasons. When mailbox achieve quota 
size and user wants to pick mails via pop3, error "-ERR Mailbox is in 
inconsistent state, please relogin." is given. I know it's because 
dovecot can't write indexes. Is it possible to force dovecot to write 
indexes with definite owner/group f.e dovecot/dovecot and not 
owner/group of mailbox? I can set quotas for user dovecot to unlimited 
and problem would disappear. Thanks in advance for any answers.

Best regards -
Chris.
