Hey,Todd,Thanks for your reply. you said " There is no need to require smtp authentication for a local user that is sending if the recipient is also a local user. "
but now the mail server suffered from spams. because the spammer know some of the senders and recipients ( local users could send mails each other), so he could easily send emails from the known local user to the another . although the mail server is not spammed as open relay ,but the spammer sometimes disrupts it. so how i could authenticate local users without rejecting the outsider? thanks very much.
