The Polspam RHSBL RBL Danger Blacklist is a domain-based blocklist (blacklist) operated by the Polish RBL server that specializes in listing dangerous domains, such as those involved in gambling or phishing activities.
The Polspam RHSBL RBL Danger Blacklist is a domain-based blocklist (blacklist) that focuses on identifying what it considers to be dangerous domain names. This includes domains associated with activities like gambling and phishing. It operates on the technical zone rhsbl-danger.rbl.polspam.pl. Mail server administrators who use this list are advised to either reject mail from listed domains outright or apply a very high spam score to them.
The policy is quite strict. This specific list is one of several operated by Polspam and is considered highly restrictive. Key characteristics of this blocklist include:
Polspam RHSBL RBL Danger Blacklist is operated by Polspam, which describes itself as a Polish RBL server. It is not a commercial company but rather a community-driven, hobbyist project. The stated goal is to combat spam and poor netiquette by making it more difficult for spammers to operate.
The organization does not accept donations or sponsorships and clarifies that it is not a provider of electronic services in a legal sense. The listings on this blacklist (or blocklist) are based on reports gathered from a community of volunteers. They do not collect personal data and request that correspondence remains anonymous, focusing on the domain and its actions rather than the individual behind it.
The delisting process for the Polspam RHSBL RBL Danger Blacklist is strict and manually handled via email. They state clearly that domains known for notorious, intentional spamming will not be removed. Delisting is reserved for one-off incidents that are believed to be unintentional.
Before you request removal, you must prepare to be completely honest and detailed. Lying or omitting information will result in your request being ignored. You must send an email that adheres to the following rules:
If a shared IP address is on the blacklist because of your domain, your actions have impacted all other domains on that IP. If you are a hosting provider, you must investigate which of your clients' domains are causing the issue. Once the spamming domains are removed, the host IP address will automatically be delisted after 7 days without any intervention.
The impact of being on the Polspam RHSBL RBL Danger Blacklist is generally considered low to moderate, depending heavily on your audience. Because it is a Polish blocklist, its adoption is likely concentrated among mail servers in Poland and Europe. If you send a significant amount of email to this region, the impact could be higher.
Polspam itself states that it does not block or ban anything. A listing is simply information that an administrator can use to make a decision. An entry on this specific blacklist will likely cause receiving servers that use it to assign a high spam score to your emails, increasing the chances they land in the spam folder or are rejected entirely. This can harm your domain's sending reputation and overall email deliverability.
