dovecot - Dec 2009 - id/permissions question

People,

There is an imap client, which runs with user1 uid, but when its accessed to 
watch a maildir, whose (and its contents) ownership is user1:user1, this error 
occurs:

dovecot: IMAP(user1): fchown(/path/user1/dovecot-uidlist.tmp, -1, 12(mail)) 
failed: Operation not permitted (egid=1000(user1), group based on /path/user1)

dovecot.conf contains this line: mail_privileged_group = mail
authentication happens through passwd-file, where for user1 its uid and gid are 
specified as in /etc/passwd and /etc/group.

So how should dovecot be told to use user1 group instead of mail group? (or it 
needs some other solution?)

This is needed only with mbox format. You should probably just comment
it out.

chgrp user1 /path/user1

or

chmod 0700 /path/user1
