The spam.rbl-dns.com is a realtime database of open-relay hosts, spammers hosts, open proxies, spam engines.
All hosts in this list are periodically (every 60 months) re-checked and the secured hosts are automatically removed from our databases.
spam contains IPs received from:
SPAM Sources
The addresses are gotten from E-Mail that we have received that was SPAM.
Bulk mailers
That don't require confirmed opt-in from their customers, or that have allowed known spammers to become clients and abuse their services.
Open Relays, hijacked PCs
IPs exhibiting characteristics which are specific to open proxies and dedicated Spam BOTs which have been abused to send spam, worms/viruses that do their own direct mail transmission.
If you have inherited such IP address space, please let us know and we will remove you, but should we get additional SPAM from your IP will be added back to the list.
Note: spam does not block SPAM comming from dynamic or no PTR networks.
spam.rbl-dns.com
DNSBL queries are structured by the inverse IP address as a subdomain of the DNSBL zone. For example, to check that the general DNspam test address of 1.2.3.4 is listed in spam, query 4.3.2.1.spam.rbl-dns.com with any NS lookup tool such as...
4.3.2.1.spam.rbl-dns.com
You will receive an address:
127.0.0.2 - Open Relay, Hijacked PCs, Spam Source
spam.rbl-dns.com is included in bl.rbl-dns.com
Attention: spam is checking only IPs and not Domain Names.
Do not use spam.rbl-dns.com to check Domain Names.
