Strange,
<http://relays.osirusoft.com/cgi-bin/rbcheck.cgi?addr=213.165.64.100>
shows that this ip-address is only blacklisted by ztl.dorkslayers.com, not
by spamcop. Spamcop.net blacklists an IP-address if more than 2% of all
mail received from it for its subscribers is reported by those subscribers
as spam. So if you have a spam run from an ISP, it's possible that it gets
blacklisted for a while by spamcop.

Don't get mad at the blacklists or people that use them however, but at
the spammers. They're the ones causing people to use such drastic measures
to prevent them from drowning in the spam avalanches that are sent out
daily...
