We send emails via the smarthost of our ISP and get bounce-mails forwarded by them. My problem is that these emails do not get distributed by our SBS Exchange 2003 to the original sender but are dumped into the BadMail folder. I guess it's because the sender of these mails is not (and cannot be) member of our domain. Do you have any idea how this can be fixed? Because it's a terrible effort to always observe the BadMail folder. Thanks a lot.
