How to deny smtp sessions to unavailable email-addresses at smtp level?
Posted on 2006-10-30
I need to be able to deny smtp sessions to my Exchange 2000 server at communication levels. I wish to receive a:
550 Invalid recipient: <XXXXXXX@domain.com>
But instead I receive a OK message and the server just sends a ndr afterwards.. I really hope to get exchange 2000 to also give a 550 Invalid recipient: <XXXXXXX@domain.com>.
Is this possible?
