Is it possible to create a reverse lookup zone (based on the following facts) so that the queried DNS name matches the server IP address - preventing domain blacklisting?
We have decided to not use our SBS (2003) for DHCP. We discontinued ISA and installed a hardware router (between server and WAN), which does dhcp. My understanding is that the router will alter the outgoing e-mail header so that the IP address of origin is no longer matches the private IP address of the server.
Due to the high cost (here) for a static IP address, we opted for dynamic address service with addresses that persist indefinitely (port 25 out is blocked). I am the only person available to manage this server (we cannot afford an admin) and I am unable to configure ISA.
My Exchange/SBS knowledge is pretty limited. The server provides a tremendous benefit, but I am self-taught and may be ignorant of some important things. Thank you for any help with this!
