[Dovecot] localhost deliver(root at vlocalhost): setgid(5001) failed with euid=8, gid=8, egid=8: Operation not permitted

[Gert Cuykens]

but deliver is already root ?

and master is set as

  master {
   path = /var/run/dovecot/auth-master
   mode = 0600
   user = mail
   group = mail
  }

root at localhost:~# ls -al /usr/lib/dovecot/deliver
-rwxr-xr-x 1 root root 563112 2008-03-31 21:05 /usr/lib/dovecot/deliver
root at localhost:~#
