I have an open relay in my exchange server and unfortunatly its being used to send out spam by hackers so i had to close the port in the router so now i can't send e-mail from home using my bussiness mail.
I need help to setp up some kinda securityso I can use my e-mail system from home and block the spamers from using my server as there relay sever.

thank you

Hi, i had the same problem before and it took sometime before someone gave me a solution.

create two virtual SMTP Servers, External Server1 is binded to your external NIC and Internal Server2 is binded to your internal NIC. E-Server1 does not have an external DNS configured and relay is disabled. I-Server2 have external DNS and relay is enabled.

in this setup, only users from inside the organization have the acess to your I-Server2 and internal NIC. Users from outside (spammers) trying to relay mail to your E-Server1 will be disallowed since E-Server1 does not have name resolution capability (no external DNS configured) and relay is prohibited.

Hope this helps.
