Yes, jcheck requires a real RFC-822 e-mail address.

I suspect the address in the example got munged from <ben at bits.org>
to <ben at bits.org> when Iris removed '@' signs in order to make
spammers' lives (a little tiny bit) harder.

I'll make a note to try to beef up the jcheck diagnostic in this
case -- right now it's just a big regex.
