KB156545 - XFOR: How to Set Up a 2nd MS-type Proxy Address for MSMail Users

SUMMARY

In the Microsoft Exchange Server Administrator program, bring up the properties of the mailbox you want a to add a new proxy address for.

Click the "E-mail Addresses" tab.

Click New and click Microsoft Mail Address.

Enter the information requested and apply.

This new proxy address must now be defined as an external postoffice on all Microsoft Mail Postoffices that are indirect via the Microsoft Mail Connector Interchange Connector postoffice.

MORE INFORMATION

Example:

Bob needs a secondary proxy address. So we give Bob a new proxy address with his old NET/PO: OLDNET/OLDPO/BOB. Now Bob has two MS-type addresses:

   MS:ORG/SITE/BOB
   MS:OLDNET/OLDPO/BOB

Now you need to go to the Microsoft Mail server and use the Microsoft Exchange Server Administrator program to create a new postoffice definition for OLDNET/OLDPO as indirect via ORG/SITE. This will allow Microsoft Mail users to mail to this address.

NOTE: Exchange users will receive non-delivery reports (NDRs) when sending mail messages to this address. This procedure only allows foreign mail systems to use the second proxy address.
