Suomispam delisting: the Finnish reputation list and how removal works

Suomispam is a Finnish anti-spam project publishing DNS blocklists aimed primarily at Finnish recipients and Finnish-language spam. Its reach is regional, so for most senders it is a minor list — unless you send to Finland, in which case it sits directly in front of the mailboxes you care about.

Two features make it unlike the automated lists. Its own documentation describes review cycles that are typically several months long, and removal rests on a credible notification from the operator responsible that the problem has been dealt with. There is no quick self-service reset here.

The zones

Return codes identify the reason: 127.0.0.2 for spam-source operations, 127.0.0.3 for escalations in severe cases, 127.0.0.4 for target sites and redirectors, 127.0.0.5 for activity judged likely malicious, and 127.0.0.99 for other reasons.

Two things to take from that table. A gl hit is a scoring signal rather than a block, so a checker reporting it as a listing overstates the problem. And 127.0.0.4 means you were listed for being a destination in spam — a landing page or redirector — not for sending it, which changes the whole investigation.

Check the right object

dig +short 9.113.0.203.bl.suomispam.net        # reversed octets of 203.0.113.9
dig +short -t txt 9.113.0.203.bl.suomispam.net
dig +short yourdomain.com.dbl.suomispam.net

Use the sending IP from a Received header of mail you actually sent, and check each sending domain and your link domains separately. Read the TXT record: the return code tells you whether this is about sending behaviour or about a site you link to.

Fix the cause before you write

Delisting rests on a credible account of what changed, so you need one:

• Purge unverified recipients. Purchased, scraped and ancient addresses are what trap-driven lists see.
• Suppress hard bounces and complainers immediately, across every tool that can send.
• Separate streams. Transactional, marketing and outreach on distinct domains or IPs, so one problem cannot take down the rest.
• Secure the perimeter. Audit SMTP auth logs for credential abuse, rate-limit web forms, check for a CMS relaying mail, rotate credentials. Severe listings are often a compromise.
• Fix infrastructure. Forward-confirmed reverse DNS, a HELO matching the PTR, SPF and DKIM passing with DMARC alignment.
• If you were listed as a redirector or target site, clean the site, remove injected redirects, and check where your redirect chains actually end.
• Publish a working abuse contact and answer it. For a project that depends on operator credibility, this matters more than it does elsewhere.

Requesting removal

The project's stated contact route is email to its own address, suomispam@suomispam.net. Write it the way a network operator would want to receive it:

• The exact IP or domain, and the zone and return code you observed.
• When the problem started and what caused it, stated plainly.
• What you changed, concretely — addresses purged, account compromised and secured, redirect removed, authentication corrected.
• A working abuse contact.
• Nothing else. No volume justification, no commercial argument, no appeal to how legitimate your business is.

Severe cases may need documented evidence that the spam flow has actually stopped, so give the fix time to be observable before you ask.

What not to do

• Do not send repeated chasing emails. A small project with month-long review cycles will not be hurried, and noise works against you.
• Do not ask for removal while the cause is live. The request is a statement that the problem is dealt with; if it is not, you are spending your credibility.
• Do not block on the grey list if you are also a receiver — the project advises against it, and acting on it will cost you legitimate mail.
• Do not assume it is irrelevant because it is regional. If Finland is a market, this list is in your path.
• Do not treat it as your main problem. A Suomispam listing almost always coexists with hits on bigger lists driven by the same cause. Fix the cause and check Spamhaus, Barracuda and the URI lists too.

While you wait

Listing cycles here outlast most campaigns, so plan for weeks rather than hours. In the meantime, keep sending to engaged recipients, keep volume modest, and measure where mail is landing per provider so you can tell when Finnish delivery resumes — the list will not notify you.

MailPilot warms mailboxes at a controlled pace, validates SPF, DKIM and DMARC, checks the lists receivers consult against your domains and IPs, and measures per-provider inbox placement daily, so a slow listing's resolution shows up as measured delivery rather than guesswork.
