My exchange server seems to be allowing the email@example.com to send & receive mail with virus attachments. My virus scanning software stops it before it sends it out or receives it. It seems like different username is sending it out with the name of postmaster being used instead.
These files are being sent to the badmail folder & causing it to be filled up. I have tried many troubleshooting options but none of them seem to have worked. The badmail problem has just became a problem a week ago. I have slowed them down to a handfull a day compared to thousands in a day.
I have not tried this yet, can the postmaster be removed as an email address?
It is hard to explain what is happening. So, it you have any questions just ask.
