The SpamCop Blocking List (SCBL) lists IP addresses reported by SpamCop's users and spam traps. It is deliberately aggressive and short-lived - entries expire automatically, usually within 24 hours of the last reported spam - so the fastest route off it is to stop the offending mail and wait.
Why an IP gets listed on SpamCop Blocking List
Blocklists add an IP when they see evidence of spam or abuse from it: mail hitting spam traps, a compromised server sending on behalf of a botnet, an open relay or proxy, or a sudden spike in unsolicited mail. Shared hosting and cloud IPs can also inherit a bad reputation from a previous tenant. Because most major mailbox providers query it, a listing here typically causes widespread bounces and spam-foldering. Treat it as urgent.
How to delist from SpamCop Blocking List
SpamCop Blocking List expires listings automatically once the spam stops, so the priority is to find and fix the source, a compromised account, a misconfigured server or a bad mailing. Most senders then clear within a day or two; a manual removal request can also help:
Delisting only sticks if the root cause is fixed first. Run the full Mail Health Report to catch the SPF, DKIM, DMARC or reverse-DNS problems that often cause listings.
