Problem
After disabling Delivery Status Notification (DSN) Extension in the Domino Configuration document (Router/SMTP -->Advanced --> Commands and Extensions), you receive the following notification after requesting a DSN:

"Message was relayed by server - Outbound Support for confirmations is not Configured".  
  
Solution
This is working as designed in Domino 6.x.
An enhancement request was submitted to Quality Engineering to prevent any Delivery Notification from being sent and has been addressed in Domino 6.0.4/6.5.2.

Excerpt from the Lotus Notes and Domino Release 6.0.4/6.5.2 MR fix list (available at http://www.lotus.com/ldd):

SPR# ELMN5VFKLK - A change in Domino 6 causes the router to properly generate SMTP DSN Relay reports when the router is unable to forward Delivery Confirmation requests to the next SMTP hop, including when the current router has outbound DSN disabled in the Server Configuration document. An override has been provided in this release to allow an Administrator to disable these Relay reports. By setting RouterDisableDSNRelayReports=1, the router will not send a relay report if outbound DSN has been disabled.
