Beware of the holiday card scam/but what's overly vigilant?

Now, we've gotten several "cards" from all sorts of completely ridiculous generic "persons" such as "a schoolmate" or "a neighbor" (like our neighbors know us at all), etc. And it's easy to delete those and forget about 'em.

Tonight, we got the following:
Title: NAME_has_sent_you_a_YouTube_holiday_video_card (note: the name is the first name of a cousin of mine, but it's an incredibly common first name)
Sender: [email protected]

And then the body of it is a bunch of stuff that our mail provider isn't d/l'ing because it's images.

Now, I know that youtube is offering some sort of holiday video card service. And the [email protected] address is legit. However, see: Spammers Hijack YouTube. Plus I'm just naturally skeptical and know that, at least when it's Hallmark, they seem to be better at identifying the sender. Then again, this ain't Hallmark, so perhaps Youtube just has a few bugs to work out.

I will contact my cousin and will ask her, just in case it is legit.

In the meantime, I report this because, if nothing else, it looks pretty dang suspicious. My suggestion to any recipient is to ask the sender -- and possibly even get in touch with YouTube and push them to better identify their legitimate holiday video card service. Because while I hate getting spam, I'd also hate to can a real holiday card.

Caveat emptor!
