In above example u can see in the 1st example the sender(xyz) is not real user of my domain , still he is able to sendmail to my real users (abhi).
You know that I can still connect to your server and send an email with address abhi@domain.com to abhi@domain.com right? Do you really want to prevent xyz@domain.com?
