First up, set the user forward rule return path to construct non-deliverable return addresses - if you're running 8.5, you can do this via the configuration document (the field is just below the one that disables mail rule forwarding). If you're pre-8.5, then you need to set the following parameter in the notes.ini:
Next, create a mail rule in your configuration document. If you have designated servers that deal with all internet e-mail, the rule should only need to be created on those servers. Set the criteria to:
When sender contains nobounce AND any Recipient contains @ AND any Recipient contains .
That *should* limit the rule to messages sent to internet addresses via a mail forwarding rule - although you'd have to make sure your users were using the Notes address rather than the internet e-mail address in their rules. You can then set the action to 'Do Not Deliver' and either silently delete the message or send an NDR.
I'm sure there's probably a hole in my logic somewhere (and I'd like to think I've missed an easier way to do this) but I think this should sort you out.
Already tested it ( also with 8.5.3 ) and it worked fine !!!
Create a Program document in the server's Domino directory:
1. Open the Domino directory 2. Select the Server view 3. Select Programs view 4. Click Add Program 5. Under the Basics tab and in the field Program name enter: nserver (for iSeries, enter server) 6. In the Command line enter: -c "quit" ( for ending the Lotus Domino Server ) -c "restart server" ( for restarting the Lotus Domino Server ) 7. Fill in the Server to run on field and also set a schedule under the Schedule tab. The server does not need to be rebooted for this Program document to take effect
Caution: If your server requires a password at start up, the server will shut down and restart, but will sit and wait for the password to be manually entered.
