Don't know if anyone else uses Berkeley derived filesystem quota, but IBM's AIX does. A little over a week after migrating from UWIMAP to DC (with mbox format unchanged) everything is clean except for this one problem: When users go over quota, when they login the next time, the folder list is blank. You can imagine the panicked calls to the Helpdesk. If their quotas are raised or re-graced, Get Mail returns the expected list. This behavior happens with a variety of clients: Pine, MacMail,TBird, Horde Webmail, etc. The index filesystem has no quota on it.
I would have to imagine the Dovecot is using (or trying to use) some space in the quota'ed filesystems which the operating system won't allow, and this results in there being an empty file that DC uses for the message list sent to the client. There are NO messages in syslog (other than the expected login and logout) indicating any problems. Our legacy setup has the inboxes in /var/spool/mail, and the folders in ~/mail. The problem can happen either place.
dovecot -n returns:
# 1.0.1: /usr/local/etc/dovecot.conf listen: *:143 ssl_listen: *:993 disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login login_processes_count: 12 login_max_processes_count: 774 verbose_proctitle: yes first_valid_uid: 200 mail_location: mbox:~/mail:INBOX=/var/spool/mail/%u:INDEX=/var/dcindx/%u mbox_dirty_syncs: no mbox_lazy_writes: no auth default: passdb: driver: pam userdb: driver: passwd Suggestions?
