my mail server is sending spams even though it is not an open relay. it is using localhost as a sender. also, when any user from my domain eg.
name@mydomain.com sends mail to a group mail eg.
group@mydomain.com a failure notice is returned with
Hi. This is the qmail-send program at mail.radiusnp.com.
