Telling Exchange about (non-Exchange) SMTP servers
Posted by Bharat Suneja at 7:59 PM
For anti-spam agents like IP Block List providers (aka DNSBLs/RBLs), and Sender ID, it is important to know about which non-Exchange SMTP servers receive inbound internet mail. This allows it to ignore the SMTP servers that belong to your organization when parsing headers (in topologies where the Edge server - or the Hub Transport server if you don't have an Edge server - sit behind other SMTP relay hosts).
In Exchange Server 2003, this can be done using Exchange System Manager by going to Global Settings | Message Delivery | Properties | General tab | Perimeter IP List and Internal IP Range Configuration | Add.
In Exchange Server 2007, this is done using the Set-TransportConfig
