How Does Yahoo Spell "Spam"?

The spam filter allegedly protecting my Yahoo Mail account from unsolicited commercial e-mail rarely fails to amuse me with its periodic ineptitude. That is, while it does keep most of the junk out of my inbox, it still lets in some of the most obvious junk mail imaginable.

(Not that other companies can be that much better--at my Hotmail/Live Mail inbox, the filter flagged a promotional e-mail from Microsoft about the Zune music player as "suspicious.")

Here's one item that arrived yesterday--a message with a subject header of "From Mrs Scott Voke ( The UK National Lottery Inc)," sent from what seems to be a randomly-generated ("info240") account at bellsouth.net:

The National Lottery P O Box 1010 Liverpool, L70 1NL UNITED KINGDOM (Customer Services) Ref: UK/9420X2/68 Batch: 074/05/ZY369

FINAL WINNING NOTIFICATION:

Dear Lucky Winner,

RE: BONUS LOTTERY PROMOTION PRIZE AWARDS WINNING NOTIFICATION

(Filling in the rest of the e-mail is left as an exercise to the reader with too much time on his/her hands.)

If this spam filter were a bouncer at a nightclub, 10-year-olds would be walking up to the bar to order drinks.
