Ah, so there is your answer. No, I'd never use Spamcop for outright 
rejection. I don't even believe that Spamcop recommends such use. 
It's useful in a scoring system, such as postscreen, and I do use it 
there.

I'm not familiar with this. If you are, and you are okay with their 
listing and delisting policies, fine. Otherwise, don't use a DNSBL 
unless you are familiar with their policies and the way it is run.

I would definitely take this out.

I'm not familiar with these lists either. Cute name. :)

Well, I still try to keep the spam out of my server. I don't want to 
help spammers in any way.

I'm not sure what parameter you are talking about. If you are 
interested in restriction classes, do take the time to read the 
"Postfix Per-Client/User/etc. Access Control" document, a/k/a 
RESTRICTION_CLASS_README.html . It probably has the answer to your 
question.
