Watermarking, checking bounced mail with sender address

[ACHA | Cor van den Berghe]

Hi all,

As I understand it MailScanner only checks the watermark on bounced email with no sender address. Is it somehow possible to have MaiScanner check the watermark on all bounced email?
Lately I get a lot of backscatter mail that have a From: address and I have no idea how to stop it
Thanks for any help you can give me

Regards,
