Abusive Hosts Blocking List

No. The AHBL blocks only IP addresses and domain names (in the RHSbl).

If you are being blocked, it is most likely because either the mail server you are using is being used by spammers, or is owned by an ISP which knowingly lets spammers use its network. It is also possible that your machine may be comprimised with a virus or trojan, or have an open proxy.

If your domain name is blocked, it is most likely because your domain is being used to support spammers and their services.

If you are unsure as to why you are blocked, see our Lookup Page, and put your domain name or mail server IP addresses in there.
