The Polspam Level 2 Blacklist (BL) is a restrictive IP-based blocklist (blacklist) from the Polish RBL server Polspam, designed to identify IP addresses associated with more severe spamming activity.
The Polspam Level 2 Blacklist (BL) is a specific DNS-based blocklist (DNSBL) maintained by the Polish RBL server, Polspam. This particular list, identified by the zone bl-h2.rbl.polspam.pl, is an IP-based blacklist. It lists IPv4 addresses and larger IPv4 CIDR blocks that have been identified as sources of spam.
Level 2 is described as a "hardened" list, indicating a more restrictive policy. Polspam advises users to be cautious with their lists marked with an "h" (for hard). They recommend integrating this blacklist with a spam filter, such as SpamAssassin, to assign a score to incoming mail rather than rejecting messages outright. Outright rejection based on this blocklist could lead to blocking legitimate emails.
The Polspam blocklist is managed by a Polish anti-spam project. It is not a commercial enterprise; instead, it is described as a hobby project built and supported by a community of volunteers. The organization's goal is to combat spam and poor internet etiquette.
The project does not accept donations or sponsorships and operates purely to inform the internet community about sources of spam based on reports it gathers. It is not a service provider in legal terms and functions similarly to other community-based anti-spam initiatives.
The delisting process for this blacklist is strict and requires full transparency. They state that they do not delist domains known for notorious or persistent spamming. A removal request will only be considered for one-time incidents that are believed to be unintentional.
Before requesting removal from this blocklist, you must ensure the underlying issue causing the spam has been completely resolved. To request delisting, you must send an email. This email must adhere to several strict guidelines:
It is important to note that they do not delist individual IP addresses upon request. An IP is listed because a domain hosted on it is sending spam. Once the offending domain is removed or stops spamming, the IP address will automatically be delisted after seven days without any intervention.
The impact of being listed on the Polspam Level 2 Blacklist (BL) is generally considered low. The operators of the blacklist state that they do not block any mail themselves. A listing is simply a piece of information for mail server administrators, who then decide how to act on it.
However, any email administrator using this blacklist (or blocklist) could configure their server to reject your mail or filter it directly to the spam folder. Because Polspam itself recommends using this specific list to score mail rather than reject it, the direct impact may be less severe than other blocklists. The primary consequence is a damaged sender reputation, which can lead to email delivery problems with providers who use this data.
