I had the same in mind but didn't post as I only run a small server
pressent days.

I utilize grossd and use several blacklists (also not that trusted ones)
to decide who to greylist and who not.

   dnsbl = blacklist.woody.ch;2
   dnsbl = bl.spamcop.net
   dnsbl = ix.dnsbl.manitu.net
   dnsbl = pbl.spamhaus.org
   dnsbl = sbl-xbl.spamhaus.org

That setup made it really good. "Normal" mailservers get their mails
delivered without any interuption and even if you end on a blacklist for
whatever reason, your mail can get delivered later.

Regards
   Klaus
