Recently a friend told me he had been sent spam from one of my email addresses, and today I got bounced spam which had that email address as recipient. This email address was connected to MSN Messenger a very, very long time ago. The domain is one of my private domains.
What makes me think that this is not just a spoofed sender is this line in the headers that I got in the bounced email:
Sender: <[email protected]>
Does this mean that someone is sending the spam using Windows Live (via SMTP) and Windows Live helps them spoof the sender? If so, would removing my account from there (which I don't use anyway) help?
