hm,  spamcop blocks too many addresses for me. so, I often
got  no  mails  from  friends  that send from big nets (like strato.de,
aol.de, 1und1.de and so on). so I don't use it anymore.

try these ones:
dul.maps.vix.com, relays.orbs.org, opm.blitzed.org, rfc-ignorant.org, cbl.abuseat.org

or if you have one more that's very good, just give me a hint :)

thx & cheers
