Exchange Address Rewrite in Exchange Server 2007

Exchange Address Rewrite in Exchange Server 2007 is already installed with the core messaging subsystem but is not enabled. You have to use the Exchange Management Shell to activate Exchange Address Rewrite.
One other new feature of Exchange Address Rewrite in Exchange Server 2007 is that you can enable this feature on a per user, SMTP domain and/or SMTP sub domain base and not for the whole Exchange 2003 Virtual SMTP Server as in Exchange Server 2003.
You configure Address Rewriting agents on the SMTP receive connector and send connector on a computer that has the Edge Transport server role installed.
Please note:The Exchange Server 2007 Address Rewrite Agent is only available on Edge Transport servers.

Troubleshooting Edge Transport Server Queues That Contain Mail Destined to a Hub Transport Server

This topic explains how to resolve issues where messages queue on a Microsoft Exchange Server 2007 Edge Transport server that are destined for delivery to an internal Exchange Hub Transport server. In the Queue Viewer, these messages display the error message 451 5.7.3 "Cannot achieve Exchange Server authentication".

This issue occurs when both Transport Layer Security (TLS) and Exchange Server Authentication are not configured on the default Receive connector of the receiving Exchange Hub Transport server. Therefore, you can resolve this issue by enabling TLS and Exchange Server Authentication on the default Receive connector.
