Great, now I'm tempted to spend way too much time experimenting to find other banned phrases. :-P But sure enough, whether it's buried in a bunch of lorem ipsum or standing alone, that phrase will send your mail to the ether. It never showed in Junk, it just never came across the wire at all. Edit: this behavior goes in both directions, BTW; receive or send.

I'd be willing to write it off as a one-time error on the part of some individual contributor, but what else will get your mail deleted? Since there are no checks in place for "rogue" ICs adding phrases on server-side, what will cause stuff to go missing tomorrow?
