Use the Sender Confidence tab on the sender reputation properties to enable or disable detection of open proxy servers.
A test for open proxy servers is one of the characteristics that sender reputation evaluates to calculate the sender reputation level (SRL). When it is enabled, sender reputation filters all external messages that come through all Receive connectors on that computer. If sender reputation verifies that the proxy server is an open proxy server, sender reputation adjusts the SRL rating appropriately. By default, detection of open proxy servers is enabled.
