bl.zonecheck.orgAs this service is based in Australia, the Courts here have already ruled that blacklists are not liable for any losses or damages that may be experienced by those in DNSBL listings, we have the legal right to list miscreants, we do not force anyone to use any of our lists, so if you're listed for spam or abuse, deal with it, clean up your act. Most of our lists are created from various honeypots, so if you're listed, it's because you were up to no good. Once you have decided to be a nice netizen, you may request a delisting if you can show you are sending legitimate Emails. We also accept the listing may relate to previous user of your IP, or a PC that has been hit with malware/viruses, in which case you need to have it cleaned up before asking for delisting. Note: We cannot and will not remove any IP's from the countries lists, as these are static RIR country allocations, they are not claiming you were a bad actor.
Our lists...
Worth remembering that once an entry is added it can remain until a delisting request is made.
We do expire entries from most lists periodically, this is usually the following durations from the last report.
