SpamCop Blocklist (SCBL) Removal

A SpamCop listing removes itself. The SpamCop Blocking List (SCBL) delists an IP automatically 24 hours after the last spam report, and SpamCop asks admins not to write in asking for early removal. So the job isn't getting delisted, it's stopping whatever is generating the reports. Once that stops, the listing ages out on its own.

For the general blocklist playbook (reading the bounce, shared IPs, what not to say to list operators), see We Got Blocklisted. This page covers what's specific to SpamCop.

What a SpamCop bounce looks like

Receivers that use the SCBL query bl.spamcop.net. A rejection typically looks like this:

554 5.7.1 Service unavailable; Client host [203.0.113.7] blocked
using bl.spamcop.net; Blocked - see https://www.spamcop.net/bl.shtml?203.0.113.7

The link at the end goes to SpamCop's lookup page for that IP, which shows whether it's listed and roughly when it's due to drop off. If the delisting time shows as 0, the IP has entered the delisting process.

How the SCBL decides to list you

SpamCop is different from most lists: it runs on reports. People who receive spam submit it to SpamCop, and SpamCop also operates spam traps. The SCBL lists an IP when the number of reports is large relative to the volume of unreported mail SpamCop sees from that IP.

The published criteria are more specific than most lists offer:

• Trap hits count heavily. For small numbers, each spam trap hit is weighted five times as much as a manual report. Beyond that, the weighting climbs faster.
• Volume matters. SpamCop estimates how much mail an IP sends from the lookups receivers make against the SCBL. An IP sending a lot of mail that nobody reports earns "reputation points" that offset reports, which is why high-volume legitimate senders are rarely listed.
• It's recent-only. Fresh reports count more than older ones, reports more than a week old are ignored, and an IP with only one report is never listed.
• It's IP-only. The SCBL doesn't list domains or email addresses, and it doesn't list anyone for missing or broken DNS or reverse DNS.

That last point is useful for diagnosis. If you're on the SCBL, it's because SpamCop users or traps received mail from that IP recently. Not because of your DNS, and not because of something you did months ago.

Common causes

In rough order of how often they show up:

1. Mail to people who didn't sign up. A new list source, an imported trade-show list, or a purchased list. SpamCop users report spam to SpamCop by habit, so unwanted mail turns into reports fast.
2. Old addresses that have become traps. Mailing addresses with no engagement for years, or reactivating a dormant list, is a reliable way to hit SpamCop's traps.
3. A compromised account or web form. A contact form or newsletter signup being abused to send to third parties, or a phished mailbox, can get an office IP listed even though nobody there sent anything unusual on purpose.
4. Forwarding. A server that auto-forwards incoming mail (spam included) to another provider can get reported for spam it only relayed.

How to get off the SpamCop blocklist

1. Confirm the listing. Use the lookup on the SCBL page and note when it was last reported.
2. Stop the source. Pause the campaign or sending stream that started around the time of the listing. If nothing obvious changed, check for compromised accounts and abused forms before anything else.
3. Look at the reports if you can get them. SpamCop files its reports with the network administrators responsible for the sending IP, and anyone can create a SpamCop ISP account to request summary reports about IP space they specify. If you run your own IP space, check your abuse@ mailbox and set up summary reports. If you're on an ESP, ask whether they received SpamCop reports for your mail.
4. Wait out the 24 hours. Once reports stop, the IP delists automatically. Delisting can take up to 4 more hours to reach SpamCop's mirrors and the servers that use the list.
5. Only contact SpamCop if something is actually wrong. SpamCop will review two kinds of problem: a technical error on its side, or a report from a user who reported mail they genuinely signed up for. For the second, SpamCop asks for the subscriber's double opt-in confirmation record. The contact should come from the IP's administrator using a role address such as postmaster@ or abuse@, with their name, title and relationship to the IP. SpamCop says it doesn't make exceptions to its posted policies, so a request that boils down to "please delist us early" won't help.

If you're on an ESP's shared IP, step 4 still applies, but steps 2 and 3 are joint work. Your ESP owns the IP; you may own the list that caused it.

How to confirm it's fixed

• The lookup on SpamCop's site shows the IP as not listed.
• Bounces citing bl.spamcop.net stop. Because receivers cache DNS answers, give it a few hours after the delisting before deciding something's wrong.
• The listing doesn't return over the following week. A relisting within days means the source is still running.

Keeping it from coming back

• Know your list sources. Every address should trace back to a signup you can show. If you couldn't produce a confirmation record for a given address, you shouldn't be mailing it.
• Sunset unengaged addresses. Stop mailing people who haven't opened or clicked in a long time. That's where traps live. The spam trap post goes through why.
• Lock down forms. Rate-limit and add CAPTCHA to anything on your website that sends mail.
• Make unsubscribing easy. A recipient who can't find the unsubscribe link reaches for the spam report button instead, and some of them report to SpamCop.

How much does a SpamCop listing matter?

Less than a Spamhaus listing, usually. SpamCop itself describes the SCBL as aggressive, says it "often errs on the side of blocking mail," and recommends receivers use it to tag or divert mail rather than block it outright. Plenty of receivers follow that advice, so a listing often means some mail lands in spam or quarantine at smaller domains rather than bouncing everywhere.

But a SpamCop listing is a symptom worth taking seriously even when the delivery impact is small. It means real people, or traps, received your mail and flagged it as spam in the last day or two. For how it compares with other lists, see which blocklists actually matter.

When to get help

If you keep getting relisted every week or two and can't find the source, or the listing coincides with a bigger delivery drop at Gmail or Microsoft, the SpamCop listing is probably one symptom of a larger data problem. That's a good time to get a second set of eyes.

FAQ

How long does a SpamCop listing last?

The IP is delisted automatically 24 hours after the last spam report, and it can take up to 4 more hours for the change to reach SpamCop's mirrors. New reports reset the clock.

Can I request early removal from SpamCop?

SpamCop asks admins not to request early delisting and may not respond to those requests. Contact them only to report a technical error or to dispute a specific report with an opt-in confirmation record.

Does SpamCop list domains?

No. The SCBL lists IP addresses only. If a bounce names a domain blocklist, it's a different list, often the Spamhaus DBL.

Is SpamCop free to get off?

Yes. Delisting is automatic and costs nothing. Any service offering to remove you from SpamCop for a fee isn't doing anything the 24-hour timer won't do on its own.
