[geeks] Spamassassin + DNSBL

[Matty]

Howdy,

Has anyone gotten DNSBL to work with Spam Assassin? I did
some googling, and came up with:

http://www.blackholes.us/docs/usage.html

I added a blackholes.cf to ~/.spamassassin, but am unsure how
to enable it (looking at the man page and default spamassassin 
output doesn't show anything). I wasn't able to find much on DNSBL 
on the main Spam Assassin website either :( I am specifically trying 
to tie SA into:

http://www.spamhaus.org/SBL/howtouse.html

If anyone has any documents or info, could you pass them
on? I have been surfing for an answer all day, and can't 
seem to nail this down.

Thanks,
Ryan
