I have a domain (domain.com) which needs to have mail forward to Exchange (domain.somedns.com) Has anyone modified their mx entry of a domain to forward to a Microsoft Exchange server? The Exchange is sitting on a sub-domain which is pointing to the Ip address of the ISP. Unfortunately the ISP is blocking port 25, but Exchange is working on port 26. I have Exim running on port 25 and 26 Besides entering the sub-domain as the mx entry... anything else that needs to be done? Geez... did that make any sense?
