I just noticed something odd on my mailserver running Courier 0.46 (yea, I know I need to upgrade).

When I have a .mailfilter that looks like this:

to "!exte@domain.com"

and the destination mailserver refuses the message for whatever reason, the DSN is sent to the local postmaster rather than being routed back to the sender. How do I fix this so that the DSN will be routed back to the proper person?

Look at the bounce message. It's actually a double-bounce. The original forwarded message had an invalid return address set. The bounce could not be delivered, due to an invalid return address, so the bounce bounced to postmaster.

You will need to identify the original return address of the forwarded message, investigate why the return address is invalid, and fix it.
