Preferably you'd use auth-userdb now instead of auth-master.

doveconf converts that just fine:

service auth {
  unix_listener /var/run/dovecot/auth-client {
    mode = 0660
  }
  unix_listener /var/run/dovecot/auth-master {
    mode = 0600
    user = vmail
  }
}

But again, auth-userdb instead of auth-master is safer.
