If you haven't already, try one of the e-mail control facilities that will simply block the senders of this rubbish. We use the ftgate e-mail server, it automatically blocks addresses that display persistent spamming/hacking behaviour and allows us to block IP ranges- even whole countries- to get some peace.

"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
