What it is

The list, in plain terms.

The NordSpam BL is the IP address blocklist of the NordSpam Project, published as the DNS zone bl.nordspam.com. NordSpam describes itself as a non-profit that tracks spammers and spam-like activity, aimed mainly at Nordic and European mail, and runs an RFC 5782-compliant DNSBL that receivers query to filter inbound mail.

The BL lists IP addresses, not domains — it is your sending server that is flagged, not the domain in your message. NordSpam publishes a separate domain blocklist, dbl.nordspam.com, for domain reputation; this guide covers the IP-based BL. A listing means mail from your IP can be deferred or rejected by any receiver that consults the zone.

NordSpam is a smaller, regional list rather than a top-tier blocklist like Spamhaus, so its reach is narrower. If your mail is bouncing, confirm from the receiving server's rejection message that bl.nordspam.com is actually the cause before you act on this listing.

Why you get listed

What a listing on NordSpam BL means.

Unsolicited bulk or commercial email NordSpam saw messages from your IP that it classes as unsolicited bulk email or spam-like traffic. This is the core reason an IP lands on the BL.

A compromised or abused host An infected machine, hijacked account or misconfigured server on the IP is emitting spam without your knowledge. The listing reflects the traffic, not your intent.

Poor sending hygiene High complaint rates, hitting spam traps, or bulk sending to recipients who did not opt in can all produce spam-like signals that trigger a listing.

How to get removed

Delisting, in order.

Removal is free. Fix the cause first — a listing you clear without a fix comes straight back.

1 Confirm the listing. Query your IP against bl.nordspam.com, or use the lookup on nordspam.com. A listed IP returns 127.0.0.2. Make sure the receiver that rejected your mail actually cites NordSpam before you spend time on this list.
2 Find and fix the spam source. Identify what sent the offending mail: clean the malware or compromised host, close any open relay, secure the abused account, and stop the campaign that drew complaints. NordSpam will disregard a removal request that does not explain how the problem was fixed.
3 Email the delisting request. There is no automated removal form. Send a request in English to [email protected] from the owner of the blacklisted IP block. Include evidence that the spam issue is resolved and an explanation of what you have done to prevent it recurring.
4 Wait for the manual review. Delisting is handled by hand. NordSpam states requests are typically investigated and processed within 1 to 48 hours when a valid explanation is provided. They may decline if the corrective action looks insufficient to prevent future abuse.
5 Re-check before resuming. Once removal is confirmed, re-query bl.nordspam.com to verify the IP no longer returns 127.0.0.2, then ramp your sending back up gradually so you do not trip the listing again.

The official route

Straight to the source.

Removal happens on NordSpam BL's own tool — never through a paid service.

Return codes

127.0.0.2 Listed — the IP is on the NordSpam BL. A TXT query returns further detail.

How long it takes

Removal is a manual, email-only process. NordSpam states valid requests are typically reviewed within 1 to 48 hours of submission. There is no self-service instant delisting, and a request without evidence that the spam problem is fixed will be ignored or declined.

Common questions

About NordSpam BL, specifically.

How do I remove my IP from the NordSpam BL? Fix the spam source first, then email [email protected] in English from the owner of the blacklisted IP block, including evidence the issue is resolved and how you will prevent it recurring. There is no automated removal form.

Does NordSpam charge to delist an IP? No. NordSpam removal is free of charge. Any third party offering to remove a NordSpam listing for a fee is a scam — no outside service can influence or speed up a NordSpam decision.

How long does NordSpam removal take? NordSpam states valid requests are typically investigated and processed within 1 to 48 hours of submission. It is a manual review, so a request without a proper explanation of the fix can take longer or be declined.

Why was my IP listed on bl.nordspam.com? NordSpam detected unsolicited bulk email or spam-like traffic from your IP. That often means a compromised host, an abused account, or bulk sending to recipients who did not opt in.

What does a NordSpam lookup return? A listed IP returns 127.0.0.2 for an A-record query against bl.nordspam.com. A TXT query returns additional detail about the listing. NordSpam uses a single positive return code rather than a table of codes.

Is the NordSpam BL widely used? NordSpam is a smaller, regionally focused list, so fewer receivers consult it than the major blocklists. Confirm from the bounce message that bl.nordspam.com is the actual cause before treating it as your delivery problem.

The bounce behind the listing.

554 5.7.1 message rejected → The permanent bounce a listing most often triggers — what it means and how to clear it. 550 5.7.1 blocked → A rejection on reputation grounds — usually the same listing, seen from the sender side. Blacklist checker → Re-check your domain and every sending IP once the cause is fixed.
