***doing this is safe it does not effect your mail flow*** Now here are the steps to configure this on Exchange 2010 server, we will create convert our Authoritative domain to Internal Relay Domain, This is how it worked on if we were doing in on E03 server Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўForward all mail with unresolved recipient to hostР В Р вЂ Р В РІР‚С™Р РЋРЎС™

E210 Receives mail goes trough the GAL and finds out the SMTP address Р В Р вЂ Р В РІР‚С™Р РЋРЎС™ is NOT a valid recipient, E210 sees the matching Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўSendР В Р вЂ Р В РІР‚С™Р РЋРЎС™ connector with same SMTP address space and instead of bouncing mail back to sender it sends the smart host defied in the send connector, which is the IP address of the mass mailing system ( ListServer) in this case.Р В РІР‚СњР В РІвЂљВ¬.ListServer accepts mail and, is the group e-mail address and ListServer sends mail to each group member. User A opens his outlook sends mail to Р В Р вЂ Р В РІР‚С™Р РЋРЎС™ User A mailbox resides on E210 ServerР В РІР‚СњР РЋРЎвЂє. Your ListServer has its own IP address when its sends mail out incase the IP getting in RBL list etc due to mass mailing.Р В РІР‚СњР В Р вЂ№. Now you created mail address called on the ListServer, and you defined bunch of external mail addresses in there. Now letР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s remember what was SMTP name sharing briefly, you have Exchange server and your SMTP name space is and you installed List server in your network because you wish to perform mass mailing and not wanting to use your Exchange server for this purpose while you will use same SMTP name space.

The propose of this configuration is most likely, sharing SMTP name space with another mailing system within your organization such as Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўListServerР В Р вЂ Р В РІР‚С™Р РЋРЎС™ etc. You will remember the option Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўForward all mail with unresolved recipients to hostР В Р вЂ Р В РІР‚С™Р РЋРЎС™ option on Exchange 2003 on the SMTP virtual server properties.
