I know a lot of DNSBLs, and I've never heard of this one before, nor do I know anyone who uses it. Are you sure it's worth any effort at all to unlist yourself? Any fool can set up a DNSBL, many fools do, most aren't used by anyone. If someone's using to block mail and you care about sending mail to that recieipient, I'd be more inclined to call the receipient and suggest he or she use some more competently run DNSBLs.
