Delivery failure

Once again someone's spoofing my email address to send out mass emails, which means I get a ton of delivery failure messages I need to sort out. Now if the recipients used the Sender Policy Framework this wouldn't be so much of a problem because none of these messages have been sent from the server they claimed to have come from.

What the receiving server does is ask the apparent sending server "Did you send this?" If the reply is no then it's most likely to be spam.
