Regarding: Mail Delivery Failed: Returning Message To Sender Starting yesterday, I am getting these Mail Delivery Failed messages from SpamCop after I report an e-mail. Everything was fine, I did everything correctly (I forward as an attachment) to SpamCop, but I immediately get something like this back: This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: submit.xxxxxxxxxxxxxxxx[at]spam.spamcop.net This message has been rejected because it has a potentially executable attachment "Winowds XP + Office XP = $80. .eml" This form of attachment has been used by recent viruses or other malware. If you meant to send this file then please package it up as a zip file and resend it. What is happening?
