	i have solved one problem that was 1st example in my previous
mail. means now no unknow user from my domain can send mail to my real
users of mydomain but still there is 2nd problem means anyone can telnet
to my server and can forge real domain address to sendmail to my domain
users like 
	telnet mail.domain.com 25

Perhaps you should consider milter-sender if you want to verify that the
sender is a valid email address.
