The Suomispam Gray List (GL) is a secondary reputation blacklist for IP addresses linked to spam sources that also have significant non-spam use. It is available through the DNSBL zone gl.suomispam.net and is intended for scoring, not direct blocking. The list is smaller than Suomispam's primary list and receives less frequent updates.
The listing policy defines spam as unsolicited bulk email (UBE). The legality of the message is not the listing test. Listings are a private reputation assessment, similar to a review. Suomispam considers the type of sending host before adding it. A shared mail server with legitimate use gets more patience to reduce collateral damage, but persistent spam can still lead to a listing. Across the Suomispam blocklist and blacklist data, entries can cover direct spam sources, spam support services, redirectors, and target sites used in spam messages.
Who runs Suomispam Gray List (GL)?
The Suomispam Gray List (GL) is operated by Suomispam, a reputation service focused on spam sent in Finnish or otherwise related to Finland. The service exists because global blacklists and blocklists do not always cover smaller countries and language-specific spam patterns in enough detail. Suomispam provides reputation data only; mail server operators decide whether to use that data in their own mail filtering.
How should you use Suomispam Gray List (GL)?
Use the GL as a low or moderate negative reputation signal inside a broader spam score. A hard reject rule creates avoidable false positives because the list intentionally includes networks with meaningful legitimate mail use.
Suomispam GL DNSBL referencetext
DNSBL zone: gl.suomispam.net Positive test: 2.0.0.127.gl.suomispam.net Response codes: 127.0.0.2 Spam source 127.0.0.3 Escalation 127.0.0.4 Target site 127.0.0.5 Suspicious 127.0.0.99 Other or uncategorized
- Query the DNSBL zone gl.suomispam.net only from mail filtering software that supports scoring or tagging.
- Use the test record 2.0.0.127.gl.suomispam.net to confirm the integration returns a positive DNSBL response before you apply a production score.
- Treat the response code as context for investigation instead of a standalone blocking decision.
- Keep authentication and reputation separate. SPF and DMARC fixes help prove which mail is authorized for your domain, but they do not remove a Suomispam listing.
- Use Suped's product to monitor DMARC reporting and authentication health while you investigate reputation changes, so blocklist (blacklist) alerts can be tied back to sending sources and domain activity.
How do I get removed and delisted from Suomispam Gray List (GL)?
Removal from the Suomispam Gray List (GL) is manual after the operators are convinced the underlying spam issue has been resolved. A credible and detailed notification from the server operator about the fix can be enough. Serious or repeated spam cases require evidence that the spam has stopped. Delisting is delayed when the operator continues to provide services, such as web hosting, to the spammer.
Before requesting removal, take these steps to avoid wasting time and improve your chances of being delisted:
- Specify the listed resource and include the exact IP address or domain shown in the Suomispam lookup. Requests without this information cannot be processed.
- Explain what caused the spam and which corrective actions you took. A bare statement that the problem is fixed does not provide enough evidence.
- Bring in your hosting provider when the listing covers a wider network range or uses a wildcard character like *. Suomispam says network-level listings require provider action.
- Verify whether your domain itself is listed. Shared hosting can cause a domain to appear connected to a listed IP even when the domain is not the listed resource.
- Keep SPF and DMARC out of the delisting argument. Suomispam says those records are not why a resource is listed and fixing them does not trigger removal.
Suomispam does not offer a public delisting form. Contact them directly by email at suomispam@suomispam.net.
What's the impact of being listed on Suomispam Gray List (GL)?
The impact of being listed on the Suomispam Gray List (GL) is generally low when administrators follow Suomispam's guidance. The list is explicitly not meant for outright blocking of mail. A listing means your email can receive a higher spam score and be filtered into junk rather than rejected outright. The practical risk is strongest for mail traffic involving Finnish recipients or operators that weight Finnish spam reputation data. Because GL includes shared infrastructure and escalations, trace the listing to the sending IP or network before treating it as a domain-level problem.
