Polspam RHSBL is a Polish right-hand side blocklist (RHSBL) that lists domain names connected to spam. RHSBL means Right-Hand Side Blacklist, the domain part to the right of the '@' symbol in an email address. Unlike an IP-based DNSBL, this list is domain and URI focused, so the main query target is the domain rather than only the sending IP address.
Mail server administrators query the zone rhsbl.rbl.polspam.pl. Polspam lists it as the main RHSBL zone for listed domain names, with an answer of 127.1.1.1. Related RHSBL zones cover hardened or observation cases, plus a danger zone for domains tied to higher-risk activity such as phishing or gambling. Polspam warns administrators to use the more restrictive zones inside spam filters or with suitable scoring, not as a blanket reject rule.
According to its policy, the goal is to combat poor netiquette and make spam operations harder. The blacklist is populated through community reports and Polspam's own analysis. Administrators who are new to this blocklist should observe results in a scoring setup before using it to reject mail directly.
Who runs Polspam RHSBL RBL blacklist?
Polspam runs the Polspam RHSBL RBL blacklist. It describes the service as a Polish RBL server and a non-commercial community hobby project. Polspam says it does not accept donations, earn revenue, or have sponsors. It also says it does not provide an electronic service in a legal sense, and that the list informs the internet community about domains reported for spam.
The operation depends on volunteer cooperation and reports from the wider internet community. Polspam states that each volunteer can report spam to the shared database, and that false entries can also be reported for review.
How to check a Polspam RHSBL listing
Because Polspam RHSBL is domain-based, check the domain against the RHSBL zone before trying to delist an IP address. For a normal domain listing, query the domain under rhsbl.rbl.polspam.pl. Hosting providers that need to audit customer domains should also check rhsbl-h.rbl.polspam.pl, which Polspam marks for domain names during recognition and recommends only for spam-filter scoring.

An A response means the queried domain has an entry. A no-answer result does not prove that all mail is healthy, because another domain on the same shared IP can still affect the IP-based Polspam blacklist. Use bounce text, message headers, and hosting records to identify the exact domain named in the rejection.
Suped's DMARC reporting and email authentication platform helps map legitimate sending sources and authentication failures before you contact Polspam, so the delisting request explains whether the problem came from your domain or another sender using shared infrastructure.
How do I get removed and delisted from Polspam RHSBL RBL blacklist?
The delisting process for the Polspam RHSBL RBL blacklist is strict and requires complete honesty. Polspam does not offer delisting for domains that it considers notorious spammers. A delisting request is only considered for one-off incidents where the sender can prove the spam was unintentional and has fixed the underlying issue.
Before requesting removal, fix the sending problem first. Polspam's rules say removal requests that do not come from a postmaster@ address, do not name the RBL list, do not include detailed rejection information, or do not state that the sender is the MTA administrator of the domain will not be considered.
Before requesting removal from this blocklist, send an email that follows these rules:
- Send plain text only. Polspam says HTML, scripts, remote tracking objects, images, logos, and similar elements can end the interaction.
- Include the domain name, the domain IP address, the exact list name, and the suspected cause of the listing.
- Explain what happened truthfully, including any deliberate spam, purchased lists, outsourced mailing, landing pages, hidden domains, or tracking.
- Do not include a personal signature. Polspam says the correspondence should be treated as domain-to-domain rather than person-to-person.
- Attach useful evidence without personal data, such as bounce text and relevant headers. Remove personal data before sending samples.
Do not request delisting of an IP address when the issue is the RHSBL domain listing. Polspam says the IP is listed automatically because a listed domain is hosted there. Once the spam activity stops and the domain issue is resolved, the host IP address is removed from the IP blocklist after 7 days without a separate request.
If you use shared hosting and your own domain is not listed, ask the hosting provider to audit all domains on the affected server. Polspam states that one spamming domain on a shared IP can lower the reputation of other domains using that IP.
What is the impact of a Polspam RHSBL listing?
The impact depends on who uses the list. Polspam itself does not block or ban email, and a listed domain can still send and receive messages. The practical risk appears when a receiving mail server uses the blacklist or a related Polspam zone in its filtering rules.
Those systems can reject mail or add enough spam score for the message to land in junk. That hurts email deliverability for recipients whose mail providers use this blocklist. Being listed damages domain reputation because it tells receiving administrators that Polspam has associated the domain or its host with spam.
