Ok, I've done: chown dovecot:dovecot /usr/local/libexec/dovecot/deliver chmod ug+s /usr/local/libexec/dovecot/deliver and set socket listen { master { # Master socket provides access to userdb information. It's typically # used to give Dovecot's local delivery agent access to userdb so it # can find mailbox locations. path = /var/run/dovecot/auth-master mode = 0660 # Default user/group is the one who started dovecot-auth (root) user = dovecot group = dovecot } in dovecot.conf. Then I got: deliver(userid): setgid(10) failed: Operation not permitted So I tried chown root:dovecot /usr/local/libexec/dovecot/deliver nd now it seems to be working ...
