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.)<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Courier New";color:#1F497D'>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.
