I do not know of a way to do it dynamically, but you could blacklist the ip space of ng.blackholes.us? Another kludge is if you have samples of the spam they send and can pattern it then you can delete it before it is sent.
That's an awful lot of address space, probably a couple hundred CIDRs.
The content analysis would be pretty iffy at best, because I've had this happen a half-dozen times in the last six weeks and it's been different stuff every time. (They're all forward-fee scams, but the text is different enough that it would be hard to match.)
I suppose I could start filtering all my network's outgoing mail - my Imail server, and a few other ones, all smarthost/gateway their email through one central server here, basically for ease of logging. I could make that server start spam-scanning too, if I had to. I'd rather prevent the spam from getting into my network in the first place, but this is probably an acceptable alternative.
