The macosxhints mail server has some spam-killing software installed, and it's done a good job at sheltering my inbox from the onslaught, but I still received over 50 of these in the last 24 hours. I've now added the above rule to my Mail rule definitions, though I choose to transfer them to a "Probably Junk" mailbox as opposed to deleting them. That way, I can review them just to be sure none are "real" emails (in particular, the "Thank you!" condition will probably catch a couple real emails).
Side note: Yes, just two hints today ... sorry, but that's the way it goes sometimes!
