I have a dual gateway servers setup in front of my IMail server. The two gateways are Imail servers also. All my Mail domains sit on the same class c address space so on the Gateways Relay Mail For: I have the Class C of all my domains and this works well. On my Main Imail Server I have Relay Mail For: My address blocks all others use SMTP Auth. I have just noticed that Say a Spammer on the following ip 192.168.0.1 claims his email address is [EMAIL PROTECTED] (which lets say is a VALID address), now he sends mail and it hits my gateway box and then forwards the mail to my Real Imail Server Which Sees the IP as my Gateway not the IP where the Email was Sent from, so the mail goes to my users, hence an open relay if he knows one of my users Email Address. What Option can I use to stop this from happening.
