About SpamCop Blocking List

The SCBL is dynamic and report-driven: an IP is listed when it accumulates enough spam reports relative to its mail volume, and it de-lists itself automatically once reports stop. There is essentially no manual appeal — the fix is to stop the spam.

Why an IP gets listed

  • Users/traps reported spam from the IP, and reports crossed the threshold for its volume.
  • A compromised account or script is sending junk through your server.

How to delist from SpamCop Blocking List

  1. 1Identify and stop the spam source (often a compromised mailbox, web form, or script).
  2. 2Once no new spam is reported, the listing expires on its own — usually within 24 hours (as little as ~12 hours for low-report IPs).
  3. 3Use the lookup at spamcop.net/bl.shtml to confirm status; a self-service delist link may appear, but it’s pointless until the spam actually stops.

Stay off SpamCop Blocking List

  • Lock down web forms and authenticated SMTP; watch for sudden outbound spikes.

Return codes

When listed, SpamCop Blocking List answers with one of these 127.0.0.x codes:

127.0.0.2Listed — reported spam source
Before you request removal: fix the root cause first — delisting while the problem persists almost always leads to a fast re-listing. Confirm the IP has valid reverse DNS, and that your SPF, DKIM and DMARC are in order.
