Why IPs typically get listed
NoSolicitado.org lists an IP when it detects unsolicited email coming from that address.
A common cause is a compromised mail server sending spam without the owner's knowledge.
Shared hosting is another common cause.
One bad tenant on a shared IP can get everyone on that IP listed.
Poor list hygiene matters too.
Sending to old, unverified, or purchased email lists raises spam complaints.
Missing authentication records, like SPF, DKIM, or DMARC, can make legitimate mail look suspicious.
Spam traps are another factor.
These are inactive addresses used to catch senders with bad list practices.
A listing on the Worst zone usually means the volume or persistence was severe.
How to check if you're listed
Start by checking your mail server logs for bounce or rejection messages.
Look for messages that specifically name NoSolicitado.org.
You can also run your IP through a DNSBL lookup tool.
Pick one that checks both zones directly.
A lookup will show whether you're on bl.nosolicitado.org, bl.worst.nosolicitado.org, or both.
Checking both zones matters. They represent different severity levels.
Each zone may need its own separate delisting request.
Several independent lookup services track NoSolicitado.org listings.
Cross checking your IP against more than one tool helps confirm the result.

How to get removed
Fix the root cause before requesting removal.
A delisting request without remediation often ends with the IP listed again.
Check your mail logs for the account, script, or customer that sent the spam.
Secure any compromised accounts. Change passwords and patch any exploited software.
Clean your sending list. Remove bounces, inactive addresses, and non-opted-in contacts.
Fix your SPF, DKIM, and DMARC records if they were missing or wrong.
Once the issue is fixed, use the delisting page on the NoSolicitado.org website.
Request a review and be specific about what you changed.
Explain the root cause and exactly what fixed it.
NoSolicitado.org has stated it reserves the right to ignore disputes it considers meritless.
A vague request risks rejection.
If your IP is on both zones, submit the request through the same site.
Treat each zone as its own listing when you confirm the result afterward.
How long it typically takes
NoSolicitado.org has not published a fixed turnaround time for delisting requests.
One sender on a hosting forum reported a delisting completed within 48 hours.
That was after waiting about a week to confirm the spam had stopped.
That single report isn't a guarantee for every case.
Processing time can vary depending on the case and current request volume.
Wait several days after fixing the problem before you submit your request.
This gives the operator's systems time to see clean sending behavior.
Submitting a request too early, before spam has actually stopped, risks a repeat listing.
FAQ
How do I run a nosolicitado.org blacklist check?
Use a DNSBL lookup tool that queries both bl.nosolicitado.org and bl.worst.nosolicitado.org. You can also check your mail server's bounce logs for rejection messages that name NoSolicitado.org directly. Checking both zones separately matters, since a clean result on one doesn't mean you're clear on the other.
How do I remove my IP from nosolicitado.org?
Fix the spam issue first, whether that's a compromised server, a bad list, or missing authentication. Then submit a delisting request through the operator's own website. Describe what caused the listing and what you fixed. Wait a few days after fixing the issue before you submit the request.
What's the difference between bl.nosolicitado.org and bl.worst.nosolicitado.org?
bl.nosolicitado.org is the general zone for IPs sending unsolicited email. bl.worst.nosolicitado.org is the stricter zone, reserved for IPs with extremely high spam volume. An IP can be listed on one or both, and each needs its own check.
Will a NoSolicitado.org listing affect all my email?
It depends on whether the mail servers you send to subscribe to this DNSBL. NoSolicitado.org is a niche, Spanish-language-focused list rather than one of the largest global blocklists. Check your bounce logs for rejections that name this list specifically before assuming it's the cause of your delivery problems.
Can shared hosting cause a NoSolicitado.org listing?
Yes. If you share an IP with other customers, another tenant's spam can get the shared IP listed. Ask your host to confirm whether the IP is shared and whether another account caused the issue. Moving to a dedicated IP can prevent this from happening again.
