Err... thats an unreleased development snapshot. Some bugs have been fixed
since then, and we have it running here as well, but I realised that the
whole thing needs to be rewritten from scratch. In the meantime, I have
to maintain it.

The upcoming Postfix 2.1 release has support for an external SMTP proxy; 
I think this is where the DCC stuff should go in for real-time spam 
rejection. For non realtime processing, use Postfix's content filtering 

If nothing better comes up in the first half of the year, I'll probably 
rewrite the whole thing for our Postfix-2.1 upgrade (and finally release
it for public use ;).
