PTR records with private IP server
PTR records with private IP server
(OP)
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!

Godaddy hosts our domain (they confirmed they cannot help) and our ISP will not do RDNS for its residential (we are now effectively) customers. So there is only the option that you mentioned. For mail relay outbound, they list 150 relays per day for $1.50, very reasonable!
Does it make sense that I configure outbound email to use 587? Thank you again
