SYMPTOMS

The LinkAge Connector version 3.2 and Microsoft Exchange Connector for IBM OV/VM version 5.5 fail to return non-delivery reports (NDRs) for messages that are addressed to non-existent Exchange PROFS proxy addresses.

MORE INFORMATION

PROFS 
      PROFS
   NODE2 (USER2)
         |
         |<- OV/VM Connector
         |
 Exchange Site 1
   NODE1 (USER1)

Address Space on OV/VM Connector in Site 1:

PROFS * cost=1

If a user in Site 1 addresses a message to an unknown mailbox, using Site 1's PROFS proxy node name of NODE1, the sender never receives an NDR. For example, if the Exchange user USER1 addresses a message to the unknown PROFS proxy address NODE1(UNKNOWN), USER1 never receives an NDR. However, if the same user addresses a message to an unknown PROFS address whose node name is not used as an Exchange Site Addressing PROFS proxy address, the sender receives an NDR as expected.
