I have used spam cop for YEARS and never had this issue until recently. I have been also getting this error message "550 AUP#SNDR Rejection Notice" on sending things to spamcop as well as just replying to some emails. The ISP says it's the email servers hosted at blue host and blue host says it's my ISP I even contacted Cloudmark customer support cm_support@proofpoint.com & they are not making any sense of this either. This just doesn't make sense that no one understands this issue and multiple people across multiple ISPs are experiencing the same issue.
