Mail delivery failed: returning message to sender
Someone or something has taken over one of my email accounts. I'm getting 30-40 returned emails a day that I didn't originate with the message as shown in my subject. Earthlink hasn't been much help and keeps coming back to saying I should run my anti-virus software (NIS 2011). I've done several complete scans but have found nothing. I have also changed my email password to something much stronger but that has not helped. I am attaching one header from a returned email. Thoughts on how to resolve this?
