But there is nothing to guarantee that the IP address(es) of the SpamCop 
relay(s) remain constant is there?  Or are they documented by SpamCop, 
and set in stone somewhere?  One assumes that load sharing, and backup 
systems will result in more than one relay being used over a period of 
time, making ad-hoc maintenance of a whitelist a bit hit and miss.  Far 
better that a commercial anti-spam company avoids the irony of being 
blacklisted in the first place ;-)
