What is Suomispam Blacklist (BL)?
The Suomispam Blacklist (BL) is a DNS-based blocklist (DNSBL) for likely sources of spam in the Finnish language or otherwise related to Finland. It operates under the zone name bl.suomispam.net. The project fills a gap left by larger global blocklists, which do not always have detailed coverage for smaller countries and specific linguistic areas.
The policy of this blacklist is to list resources based on unsolicited bulk email (UBE), which Suomispam defines as spam. The legality of the email in the sender's country is not the deciding factor. Suomispam operates as a private reputation service and publishes its opinion on sender reputation. Mail server operators decide whether to use that data for filtering.
Listings are considered case by case. Suomispam assesses the type of sending host before listing it. A shared server with legitimate traffic is treated with more patience than a server that appears to exist only for spam. Persistent spam still leads to a listing. This blocklist also includes:
- Operators with a known history of supporting spam.
- Entire networks that are significant sources of spam or appear to be snowshoe ranges.
- Spam support services, including bulletproof hosting providers and spam list vendors.
- Spamvertized sites, redirectors, and other destinations promoted in spam messages.
Who runs Suomispam Blacklist (BL)?
The Suomispam Blacklist (BL) is run by Suomispam as a private spam reputation service. Suomispam itself does not block emails. It publishes findings and data, which mail server operators and administrators choose to use when filtering incoming email. Suomispam provides the information, and the user of the blocklist decides whether to act on it.
How Suomispam BL return codes work
A Suomispam BL lookup returns an A record that identifies the listing reason. This matters because a spam source, a wider network escalation, and a target site need different remediation work.
- A 127.0.0.2 response means Suomispam sees the resource as a spam source.
- A 127.0.0.3 response means escalation, often a broader listing where the spam problem is severe enough to include more than the direct sending host.
- A 127.0.0.4 response means target site, such as a redirector, spam site, or other destination promoted by spam.
- A 127.0.0.5 response means suspicious activity that Suomispam considers likely malicious and not adequately explained by the provider.
- A 127.0.0.99 response means another reason or an uncategorized listing.
How do I get removed and delisted from Suomispam Blacklist (BL)?
The delisting process for the Suomispam blacklist is based on trust and verification. An IP address or domain can be removed once Suomispam is convinced the underlying problem has been solved. For less severe cases, a credible notification from the operator about fixing the issue is enough. For serious spam issues, proof that the spam has stopped is required. Suomispam lists suomispam@suomispam.net as its contact route.
Before requesting removal, work through these checks:
- Identify the exact IP address or domain on the blocklist. A delisting request is not useful unless Suomispam knows which listing you are asking about.
- Fix the root cause and describe the fix clearly. Suomispam says SPF and DMARC records are unrelated to its listings, so changing those records alone does not resolve a Suomispam BL issue.
- Use Suped's DMARC reporting to confirm which services are sending mail for your domain and whether unauthorized sources exist. That evidence helps your internal investigation, but it does not replace fixing the spam source or contacting Suomispam.
- Understand that whitelisting is not an option. Suomispam does not offer a whitelist, and wildcard network listings need action by the hosting provider or network operator.
- Verify the listing source directly. Some third-party lookup results confuse shared hosting with a domain listing, so confirm whether your specific domain or IP is actually listed.
- Allow time for review. Old IP listings are reviewed automatically and manually, but the cycle can run for several months unless new information triggers faster review.
What's the impact of being listed on Suomispam Blacklist (BL)?
The impact of being listed on the Suomispam Blacklist (BL) is usually low for most senders because it is a specialized blocklist with a narrow focus.
The risk is higher when you send to Finnish recipients, operate Finnish-language campaigns, or rely on infrastructure that Finnish mail operators filter closely. If your audience is outside Finland, the direct deliverability impact is usually limited. Still, any blacklist or blocklist listing is a warning sign for sender reputation and should be investigated before it affects abuse handling, customer mail, or provider relationships.
