I only have Declude A/V running on our server, so that may be correct. However, it is MUCH more efficient to block the SMTP transmission based upon a DNSRBL before the spam gets through, than accepting the message (and having to process it) in the first place. If you accept the message for delivery (rather than blocking) then you have to decide what to do with the message as well (bounce? deliver to recipient? tag? use in a weighting system?). That takes mucho more resources and is a much bigger headache from a policy standpoint.
I would rather just return a 5XX reject message to someone that is on SpamCop. Let their mail admin deal with their blacklisted server problems. Better them than me. I guess that all depends upon your religion though, and whether you lean more towards Len or Scott's viewpoint of what should be blocked. I see merits in both arguments, but on the most reliable DNSRBLs I use, I would much rather block than waste all that processing on filtering.
