spamhaus, spamcop and sorbs

Beware the people attacking spamcop, many of them dont like the way that 
if their users send to one of spamcops "traps" they will block you, which 
is fair enough, as the trap addresses are not real and not advertised.

On a network processing 1700 messages per minute, no complaints and no 
more false positives then any other RBL, and we had maybe 2 or 3 
complaints a month about RBL blockings, we have about 3 a day panicing 
cause of MS's phishing warning :)

One thig with SORBS though, they will block any server, including hotmail, 
though its only the particular server in the cluster, so you'll probably 
get most through without noticing anything out of the ordinary, the safest 
way would be to whitelist in your MTA, then let MS deal with 
whats spam. It's not that much of a problem really, as your in au and 
maybe wondering about consequences here, Optus use them.
