There is a permissions issue in dovecot 2.21 in the ~/run directory (mine is /var/run/dovecot) at least in Debian 8.
Files created by dovecot imap:
srw------- 1 root root 0 Feb 3 16:46 imap-hibernate srw------- 1 root root 0 Feb 3 16:46 imap-master
changed to make work:
srw-rw-rw- 1 root root 0 Feb 3 16:46 imap-hibernate srw-rw-rw- 1 root root 0 Feb 3 16:46 imap-master
Errors were reported in /var/log/dovecot.log which we use mainly for fail2ban (it gets huge, but ...)
vpopmail version 5.4.33 with one patch
I don't think this is a Debian issue ... possibly could be a vpopmail issue, but it's probably caused by the fact that imap daemons are running as vpopmail:
vpopmail 30182 9187 0 15:02 ? 00:00:00 dovecot/imap
What purpose does vpopmail serve that dovecot alone does not? Isn't it just an ancient leftover from historic qmail times?
