I have virtual server on exchange for incoming message. For antispam purpose, I switch on to perform reverse DNS lookup, but when I try to telnet my server from outside and to send helo like some unexisting server all work. What may be wrong? Thank for any answer.

Alexus,

Try moving the antispam software to a machine that exchange is not installed on then try the helo command. If it still works your antispam software is configured incorrectly. Make sure you are logged into the machine with a user that is not in your domain.

regards

RM
