isolate outbound mail to specific smarthost?
So my company has some internal applications that send bulk email to our clients that sometimes is interpreted as SPAM (by receiving ISPs) even though it is not. Currently this email is sent through ourcorporate Exchange infrastructure along with all regular employee email. I want to isolate this bulk email to utilize its own external ip address in case we get put on any blocklists it wont effect our regular corporate email. Is the best way to handle this to use a separate sending domain for the bulk mail and route it through a dedicated Edge transport server that only handles bulk mail? I know on other smtp servers they allow certain mail to go out different network interfaces specifically to address this issue. What is the best way to handle this situation?

Hi, As to this issue, please try to use Linked Connector. Before going on, please first understand the concept of the Linked Connector. That is Send Connector and Receive Connector can be linked together so that mail that is received via a specific Receive connector is always forwarded or pushed out a specific Send connector. Initially, we must create a Receive connector to only accept the email comes from the application by specifying the IP address of the application in the Network tab. After that, please create a new send connector which is linked to the Receive connector to send the email. The detail information you can refer to the link as below: http://technet.microsoft.com/en-us/library/bb201724(EXCHG.80).aspx In the parameter, please specify the Edge server as the Smarthost. Then the email being sent from the application will use the IP address of the Edge server. Thanks Allen
