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

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

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?)

chgrp user1 /path/user1

or

chmod 0700 /path/user1
