How to remove your IP from SpamCop (SCBL)

The SCBL removes IPs automatically once reports stop. There is no form to fill in — here is what a listing means and how it clears.

What it is

The list, in plain terms.

The SpamCop Blocking List (SCBL), published at the DNS zone bl.spamcop.net, is a list of IP addresses that have recently transmitted email reported as spam by SpamCop users. It is operated by Cisco Systems and built entirely from automated reports and user submissions, then queried by receivers to block or filter mail.

The SCBL is deliberately aggressive and short-lived. It lists an IP when the volume of recent reports against it crosses a threshold relative to the mail it sends, and it weights the most recent reports far more heavily than old ones. Reports older than a week are ignored entirely.

Because it lists IP addresses rather than domains, it is your sending server that is flagged. SpamCop itself recommends receivers use the list to tag or filter rather than hard-reject, so the impact of a listing varies by which providers consult it.

Why you get listed

What a listing on SpamCop (SCBL) means.

Reported spam from your IP SpamCop users and automated systems reported mail originating from your IP as spam. Enough recent reports relative to your sending volume pushes the IP over the listing threshold.

A compromised or abused machine A hijacked account, malware-infected host, or open relay on the IP is sending spam without your knowledge. The reports are real even though you did not intend to send them.

Spamtrap hits Mail reaching SpamCop spamtrap addresses is weighted heavily. Sending to purchased, scraped or stale lists that contain trap addresses is a common trigger.

Shared or neighbouring IP reputation On shared sending infrastructure, another customer's spam from the same IP can list it. Only complaints about the source of spam count — hosting or content complaints do not.

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 and read the reports. Look your IP up at the SpamCop lookup on spamcop.net. The result shows whether the IP is listed and, where available, the reports and the time remaining before it clears. This tells you what is actually being reported.
2 Stop the spam at the source. Find and fix the cause: secure the compromised account, remove the malware, close the open relay, or stop mailing lists that hit spamtraps. The SCBL keeps relisting an IP for as long as fresh reports keep arriving, so nothing else matters until the reports stop.
3 Do not request early removal. There is no manual delisting form and SpamCop does not honour requests to remove an IP early. Their own answer is that you cannot be removed on request — the list is time-based and clears itself. Writing to ask for removal does nothing.
4 Wait for automatic expiry. Once no new reports arrive, the IP delists automatically. An IP with sustained reporting clears about 24 hours after the last report; a lightly-reported IP (as few as two reports) expires within about 12 hours. Allow extra time for the change to reach mirrors and downstream users.
5 Re-check before you resume sending. Confirm the IP is clear at the SpamCop lookup before ramping mail back up. If it relists, reports are still coming in — the underlying cause is not fully fixed.

The official route

Straight to the source.

Removal happens on SpamCop (SCBL)'s own tool — never through a paid service.

Return codes

127.0.0.2 IP is listed on the SCBL (the only code the zone returns)

How long it takes

The SCBL is automatic and time-based. Once new spam reports stop, a well-reported IP clears roughly 24 hours after the most recent report, and a lightly-reported IP within about 12 hours. There is no way to speed this up manually, and every new report resets the clock. Allow additional time for the delisting to propagate to mirrors and to the receivers that query the list.

Common questions

About SpamCop (SCBL), specifically.

How do I get my IP removed from SpamCop? You do not remove it manually — there is no delisting form. Stop the spam reports at their source and the SCBL delists your IP automatically, typically within 24 hours of the last report. SpamCop states plainly that you cannot be removed on request.

How long does a SpamCop listing last? It is time-based. A sustained listing clears about 24 hours after the most recent report; an IP with only a couple of reports expires within about 12 hours. Any new report restarts the countdown, so the cause has to be fixed for the clock to run down.

Does SpamCop charge to delist my IP? No. Delisting is free and automatic. Any service offering to remove a SpamCop listing for a fee is a scam — no third party can influence or speed up an SCBL expiry.

I fixed the problem but I am still listed — why? Either reports are still arriving, or the previous reports have not yet aged out. The SCBL weights recent reports heavily; give it time with no new reports and it will clear on its own. Requesting early removal will not help.

Why is my IP listed when I never sent spam? A compromised account, infected host or open relay on your IP may be sending without your knowledge, or you may share an IP with another sender who spammed. Only reports about the source of spam list an IP — check for abuse and for mail hitting spamtraps.

Should I email SpamCop to ask for delisting? No. SpamCop asks administrators not to write in requesting early delisting after fixing a problem. The system removes the IP automatically once reports stop, so your effort is better spent confirming the abuse is gone.

The bounce behind the listing.
