If any IP is not on this list, and matches the 127.0.0.3 or 127.0.0.5 criterias, please let us know at firstname.lastname@example.org. We will be grateful for any help.
The 127.0.0.4 result is just for corporate messaging. This means that service will only be used to exchange common business messages. This type of listing is a service paid by the company that owns the service. If you have received any e-mail marketing from any service listed with this result, please complain it at email@example.com. Any company that does not comply this restriction will have their service summarily removed from this list.
The 127.0.0.5 result points to bulk providers with low SPAM volume. So if the same IP is listed in other DNSBLs, it is recommended to neutralize these other results because there is high probability of incurring false positive due to other customers using the same service to send desirable content.
If your organization has a message delivery service just for business purposes, that does not submit marketing content, we can include your service on this list for only $1 per IP address or domain. If you are interested in this service, please contact us for details.
IMPORTANT: We make no guarantees, despite our best efforts to maintain a stable and consistent system. Use at your own risk and take into account that our system works on the basis of reputation and without perks, so that SPAM can even be released from reputable services.
IMPORTANT: Current limit of one query every 100ms per IP block. Lower frequencies require contribution. Please get in touch with your IP or range of IPs for details.
