I am trying to setup Sender's Policy Framework (SPF) on my exchange 2003 SP2 servers, in a clustered environment, using a frontend and a backend mailbox solution. I am not sure it is configured right. When I follow the instructions as outlined in an article, to configure the Froned exchange server:
I get an error that states" Sender ID Filter must be configured globally on the the message delivery property pages. Go to the message delivery object's property pages under Global Settings to configure Sender ID Filtering"
In the Sender IT Filtering tab of the Message Delivery Properties, I have it set to Accept(SenderID status will be attached to the message for further anti-spam processing.
