SMTP Receive Connectors Test
Smtp Receive connectors are configured on computers that are running Microsoft Exchange server 2007/2010 and that have Hub Transport and Edge Transport server roles installed. The Smtp Receive Connector represents a logical gateway through which inbound messages are received. This test monitors the statistics of smtp receive connectors.
Using this test, you can periodically observe the traffic conducted by the Receive connectors, and be promptly alerted when the connector rejects messages.
Target of the test : A server configured with the Hub Transport role
Agent deploying the test : An internal agent
Outputs of the test : One set of results for each receive connector on the Hub Transport server being monitored.
