SYMPTOMS

When you send a message to a recipient on a remote Exchange Server computer, via an SMTP address, the automated delivery receipt will always be from POSTMASTER@<local_domain.ext>.

STATUS

The behavior has been changed in the latest service packs for Exchange Server versions 5.0 and 5.5. A supported fix is now available, but has not been fully regression-tested and should be applied only to systems experiencing this specific problem. Unless you are severely impacted by this specific problem, Microsoft recommends that you wait for the next Service Pack that contains this fix. Contact Microsoft Technical Support for more information.

MORE INFORMATION

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.

After the above hotfix or Service Pack is applied, you can set the registry parameter to override the postmaster address.

1. Specify the SMTP address identified as the postmaster by setting the following registry value:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS

         \ParametersSystem
   

   Name: System Administrator's SMTP Addr Type: REG_SZ

2. Set the value to the SMTP address you want to use in place of Postmaster@localDomain.ext.
