and got back:-

Looking at the original mail properties, I found the following:-

References: <BAY1-F13r2UAaTzvb5Y00006265@hotmail.com>

The reply address was known to me and I have never had this response before.
How did spammers get my e-mail address from my outgoing mail? and what are
they spamming?
