[Dovecot] setgid on directories

B> Group always is "wheel". Autocreating ignores gid from DB and uses the B> group of the parent directory - in this case /var/mail.

TSS> Does /var/mail directory have setgid bit enabled? See if chmod TSS> g-s /var/mail helps. For the record: BSD always inherits the group from the parent directory, even without its set-group-id bit being set.
