Pedantic.org Blacklist Removal: Fix Spam & Netblock Listings

To remove your IP from pedantic.org, email webmaster@pedantic.org and describe what you fixed. This applies to spam.pedantic.org, which lists IPs that sent spam directly to the list owner. A separate zone, netblock.pedantic.org, flags IPs with dynamic-looking reverse DNS and uses a different fix. Both are run by one person, not a company, so the process is simpler than most blacklists but also less automated.

What this operator checks, and who it affects

,This operator runs an RBL/ORDB-style DNS lookup service for blocking people who have sent spam to them directly,. It is a personal list, not a commercial spam-filtering company.

spam.pedantic.org lists IPs that the operator personally received spam from. It works like most DNSBLs. ,Your mail server sends a DNS query for the reversed IP address plus spam.pedantic.org, and gets back 127.0.0.2 if that address is listed,.

netblock.pedantic.org is different. ,It's a personal list of addresses that appear to have dynamically or procedurally assigned reverse DNS entries,. It doesn't track spam behavior at all, only how your reverse DNS looks.

Because this is a one-person operation, both lists affect anyone whose mail server this operator has interacted with. That's a narrower footprint than something like Spamhaus, but it can still block delivery to any recipient whose mail server queries these zones.

Why IPs typically get listed

For spam.pedantic.org, the cause is direct: your IP sent spam to the operator's own mail system. This usually means a compromised mail server, an infected machine on your network, or a misconfigured relay that let spam through.

Shared email platforms can trigger this too. ,If you're using a shared email server from a provider like Google, that provider needs to handle the issue and contact the operator directly,.

For netblock.pedantic.org, the cause has nothing to do with spam volume. Your reverse DNS record just looks like a dynamic residential or ISP-assigned address, even if your IP is static.

Common patterns that trigger this include hostnames with embedded IP octets, generic ISP naming templates, or no reverse DNS customization at all. Many legitimate static business IPs still get caught here if the ISP assigned a generic PTR record.

How to check if you're listed

The fastest way is a multi-blacklist lookup tool that queries both zones by IP. Manual DNS lookups work too, if you know the query format for each zone.

For spam.pedantic.org, query the reversed IP against that zone and look for a 127.0.0.2 response. Several third-party monitoring tools reference a lookup page on the operator's own site for checking why a specific IP was listed, though you should confirm that page still works before relying on it.

For netblock.pedantic.org, the check is the same DNS query pattern, just against the netblock zone name instead.

Running both checks together matters, since one IP can be listed on one zone and not the other, or on both at once.

How to get removed

The two zones need different approaches, since they track different problems.

For spam.pedantic.org:

1. Confirm the listing and identify what sent the spam, whether that's a compromised account, malware, or an open relay.
2. Fix the underlying problem completely before requesting removal.
3. ,Email webmaster@pedantic.org with a description of what was done to solve the problem that allowed that address to send spam,.
4. If you're on a shared platform, have that provider make the request instead of doing it yourself.

For netblock.pedantic.org:

1. ,Get a valid reverse DNS entry set up for the IP, one that doesn't look dynamically or procedurally assigned,.
2. Work with your hosting provider or ISP to set a static-looking PTR record if they haven't already.
3. Email webmaster@pedantic.org once the new reverse DNS record is live and has had time to propagate.

Neither zone appears to have a self-service removal form. Both rely on a direct email to the operator.

How long it typically takes

There's no published turnaround time for either zone. Since this is a personal list run by one individual, response times will vary more than they would with a staffed operation.

Reverse DNS changes for netblock.pedantic.org also need time to propagate before the operator can verify them. Build in a few days for DNS propagation alone, on top of whatever time the email review takes.

FAQ

How do I do a pedantic.org blacklist check?

Query your reversed IP address against spam.pedantic.org and netblock.pedantic.org separately using a DNS lookup tool. A 127.0.0.2 response means you're listed on that zone. Multi-blacklist checking tools can run both queries at once, which is faster than checking manually.

How do I remove my IP from pedantic.org?

Fix the issue that caused the listing first. For spam.pedantic.org, that means stopping whatever sent spam. For netblock.pedantic.org, that means getting a proper static-looking reverse DNS entry. Then email webmaster@pedantic.org describing what you fixed.

Why does pedantic.org keep re-listing my IP?

If the underlying problem wasn't fully fixed, expect a relisting. For spam.pedantic.org, that usually means the compromised system is still active. For netblock.pedantic.org, it means your reverse DNS still looks dynamic even after a change request.

Is pedantic.org a major blacklist that affects most mail servers?

No. It's a small, personally operated list rather than a large commercial DNSBL. Its overall reach is smaller than lists like Spamhaus, but any receiving mail server that queries it can still block or filter your mail.

Can I get removed from netblock.pedantic.org without changing my DNS?

No. The listing is based entirely on how your reverse DNS record looks, not on any spam activity. You need a reverse DNS entry that doesn't resemble a dynamic or ISP-template name before removal is possible.
