Assuming that Receive connector is on its own IP address: I’d set those two addresses up as Contacts, then use a transport rule that checks for a Received header that matches a text pattern of the IP address of the Receive connector. Bounce or drop any email except if it to one of those allowed addresses.
From: Beahm, Keith [mailto:[email protected]] Sent: Tuesday, April 10, 2012 4:02 PM To: MS-Exchange Admin Issues Subject: control of SMTP submissions Importance: Low We have several document scanners that as part of their valid business use send emails to external recipients (i.e. exactly two unique external addresses), and our security architect would like to ensure that no other recipients can be sent to using this device. I have set up a receive connector to restrict access based on the sender’s IP address, but I don’t see how to regulate HUB traffic based on the Receive Connector. The device in question allows users in the know to edit the sender’s address and the recipient address. Any suggestions or pearls of wisdom would be greatly appreciated. Thank you in advance for your time and trouble. Keith D.
