What are your watermark settings in MailScanner.conf? The idea behind
a watermark is outbound mail gets watermarked. Bounces include the
original headers so the watermark should be in it if it came from you.
If there’s no watermark it implies it’s a forged NDR. (You probably
already understand all that – just being pedantic.)
Can you check your outbound messages to verify they’re getting
watermarked? Maybe post some examples to pastebin. It’s hard to say
w/o seeing the actual message headers. Post your watermark settings
too. Naturally you’ll want to munge the “Watermark Secret” to something
other than the actual value you use.
