The Polspam Blacklist (BL) is an IP-based blacklist operated by the Polish RBL server, designed to help stop spam by maintaining a blocklist of IPv4 addresses known for sending unsolicited emails.
The Polspam Blacklist (BL) is a Polish RBL (Real-time Blackhole List) server that publishes blacklists of spamming domains and IPv4 addresses. Its primary goal is to combat poor netiquette and disrupt the activities of spammers. It operates like many other DNS-based blocklists, providing information that mail server administrators can use to filter incoming email.
Technically, this blacklist (or blocklist) focuses on listing IPv4 addresses associated with spam. The operators advise that the safest way to begin using the service is to integrate it with a spam filter like SpamAssassin. This allows administrators to assign a low score to listings initially and observe its behavior without immediately rejecting mail. They specifically warn users to be cautious with lists marked with an "h", as they are very restrictive and using them to reject mail outright can lead to unintended consequences.
Polspam Blacklist (BL) is described as a non-commercial, community-driven project. It is managed as a hobby based on cooperation with the wider internet community. The project does not accept donations or sponsorships and is not a legal service provider. Its function is to inform administrators about domains and IPs reported by volunteers for sending spam.
The delisting process from this blocklist is manual and requires direct email correspondence. The operators state they will not delist domains known for notorious spamming. Removal is considered only for one-off incidents that are not believed to be intentional or part of a larger spamming operation. There is no public delisting form; you must send an email.
Before requesting removal, you must adhere to very specific guidelines for your email:
The operators stress that an IP address is typically listed on the blacklist because a domain hosted on it is sending spam. If the problematic domain ceases its spamming activity, the host IP address should be delisted automatically after seven days without any intervention. If your domain is on a shared IP address, you must work with your hosting provider to identify and remove the offending domain that caused the IP to be blocklisted.
The impact of being listed on the Polspam Blacklist (BL) is generally considered low for global senders, but can be higher for those specifically targeting recipients in Poland. A listing on this blocklist does not automatically block or ban emails. Instead, it serves as a flag to receiving mail servers, whose administrators ultimately decide how to classify the mail. An entry simply means the domain or IP has a history of sending spam, which can lead to emails being filtered into the spam folder or rejected, depending on the recipient's server policies.
