Hi All,I am able to receive email with my current setup. MX server pointing to Host (a) record. Can SMTP to port 25. Netdiag shows that DNS is configured properly. Also get proper response internally to nslookup setq=mx. Virtual smtp connector set to * .

You say "I am able to receive email with my current setup" Do you mean unable?You also said you can "SMTP to port 25". What does this mean? Are you using telnet to simulate an SMTP session? if so can you post the text here for review? does it say mail submitted to queue at the end of the conversation?What anti-spam/virus software is installed on the Exchange server?What version of Exchange are you running?
