IMPORTANT: This article contains information about editing the registry.
Before you edit the registry, make sure you understand how to restore it if
a problem occurs. For information about how to do this, view the "Restoring
the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help
topic in Regedt32.exe.
SUMMARY
This article explains how to reroute messages through the Microsoft Exchange Server information store before sending to the Internet. Enabling the rerouting adds some advantage because the rerouted messages have more readable addresses. These messages are re-routed through the information store by using the Registry Editor (Regedt32.exe) to set the following registry value to 1:
WARNING: Using Registry Editor incorrectly can cause serious problems that
may require you to reinstall your operating system. Microsoft cannot
guarantee that problems resulting from the incorrect use of Registry Editor
can be solved. Use Registry Editor at your own risk.
For information about how to edit the registry, view the "Changing Keys and
Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete
Information in the Registry" and "Edit Registry Data" Help topics in
Regedt32.exe. Note that you should back up the registry before you edit it.
If you are running Windows NT, you should also update your Emergency
Repair Disk (ERD).

Value Name: RerouteViaStore
Data Type: Reg_Dword
Data: 1
MORE INFORMATION
When this registry value is set to 1, it internally enables two parameters required for this option to work, if they aren't already enabled, namely the P2Resolve and AddressRewrite parameters.
If you enable rerouting of the Internet Mail Service object, then outbound messages are rerouted through the information store instead of being re-sent or "bounced" as normal. The Rerouting tab is located on the Internet Mail Server Routing property page, in the Configuration container.
Enabling rerouting adds some advantage because the rerouted message's P1 and P2 From field, and P2 recipients are replaced with any locally matched custom recipient's reply address. Addresses without matching custom recipients are not altered. P1 recipients continue to be rewritten in accordance with the routing table.
