Just a note, it's not from someone with an @me.com address, it's to someone (including you) with @me.com addresses. Just report it as spam, and your filter will grab it. Enough of them come through and Apple will probably pick up on the origin and block it as well, but such is the nature of computers and email. They're just guessing likely email addresses and blasting out spam to any and every address they can come up with, regardless of whether it's a valid email address or not.
