We have an IIS smtp gateway. It lists the domains that should be forwarded to our Exchange Server. How can our SMTP relay forward spam to an internal users mail box when the email domain name is not listed on the SMTP gateway
This is in the SMTP header - computerresouces is not here and is not listed as domain in the SMTP gateway. The MX record for computerresources is also some other IP address.

The Gateway should have sent back a message "cannot relay for . . ." since its not our domain.
