They haven't yet determined that it is spam. So, RFC nitpicking wise,
they are right.
On the other hand, from a mail operations standpoint, I personally feel
that sender verification, graylisting and other methods that rely on
4xx'ing email are a bad idea, as they makes things inconvenient for a
whole lot of ISPs ... and because these emails have to be either 5xx'd
or trashed sometime sooner or later.
