This is a bit of an odd situation... I recently received an email with the message line "Looking for the sources to Boston: Mouse in the Sewer", containing only "TIA!" (Which I'm guessing is "Thanks in Advance") as the message content.

The odd bit: Mail says that it's from <insert email here because it can't be a good idea to publicly post the email address>@apple.com.

What's up with this?
