I'm getting a ton of emails to my domain address(es) with the subject saying "Mail delivery failed: returning message to sender" or "Warning: message 1BVvoA-0006c8-Rw delayed 24 hours" (or similar). I haven't sent anything from my emails in months and months. Has/is someone spoofing my email address?
I'm getting at least 100 a day of these clogging my inbox.
I heard on TechTV that the spoofing occurs when the virus/worm infected computer has your email in their address book. But is there anything I can do at this point?
This sucks.
