ok the rights can be a bit confusing at times
assuming you are running virtual users (or not)
try these one at a time, i found that when dovecot starts it will adjust
the permissions on the control files accordingly to what is set in the
examples below, also note postfix can be a variable in this but would
probably not be
I had to fiddle with stuff a lot
also dovecot i start in my rc.local (root startup)
the root user starts dovecot, it then changes everything rights wise as
stated below and then changes to user dovecot (vmail whatever) to
auctually start processing emails etc.
Again this is a pretty loose explanation but will point you in a
direction for troubleshooting.
I typically use in dovecot.conf
---------------------------------------------------------
service aggregator {
process_limit = 1000
#vsz_limit = 1g
fifo_listener replication-notify-fifo {
user = vmail
group = vmail
mode = 0666
}
}
service lmtp {
process_limit=1000
vsz_limit = 512m
client_limit=1
unix_listener /usr/home/postfix.local/private/dovecot-lmtp {
group = postfix
mode = 0600
user = postfix
}
}
service doveadm {
process_limit = 0
process_min_avail = 0
idle_kill = 0
client_limit = 1
user = vmail
inet_listener {
port = 12345
}
}
service config {
unix_listener config {
user = vmail
}
}
service anvil {
process_limit = 1
client_limit=5000
vsz_limit = 512m
unix_listener anvil {
group = vmail
mode = 0666
}
}
service auth {
process_limit = 1
client_limit=5000
vsz_limit = 1g
unix_listener auth-userdb {
mode = 0660
user = vmail
group = vmail
}
unix_listener /var/spool/postfix/private/auth {
mode = 0666
}
}
service stats {
process_limit = 1000
vsz_limit = 1g
unix_listener stats-reader {
group = vmail
mode = 0666
}
unix_listener stats-writer {
group = vmail
mode = 0666
}
}

Happy Monday !!!
