Problems with spam!

I've been having some problems with unsolicited messages. I tried checking my mail header, the To: field doesn't show my address, I wonder how the mail got into my mailbox, any idea to help me trace down that crook? I do observe something wierd, in the To: field (see pic attached), in contains @msn.com, is it an exploit in Hotmail that'll allow some idiot to send a message to everyone on Hotmail?

i hope it helps:

I can see from the pic that hotmail has a block feature. I suggest that you use it. Also anyone can use telnet to send e-mail to your address but say that it is to [email protected] and that it is from [email protected]. It only takes a little effort.

That says who it is TO. which means you can put anything like:

[email protected] <[email protected]>

I'm afraid this won't do xiao any good, but this is what I found at slashdot yesterday - a distributed spam reporting and filtering thingy... someone using this? Does it work? It sounds pretty nice to me...
