How to get removed from Mailspike Z (Zero hour)

Mailspike Z (Zero hour) removes entries automatically when the activity stops, and also accepts removal requests.

  1. 1 Find the cause on the sending host: a compromised mailbox or script, an open relay, a missing or generic PTR record, a sudden volume spike or a stale list hitting spam traps.
  2. 2 Fix the cause before asking for removal. A list that relists you quickly usually takes longer to remove you the second time.
  3. 3 Wait for automatic expiry, or request removal sooner at https://mailspike.org/anubis/.
  4. 4 Re-check the IP address here after the next zone update to confirm the listing is gone. Monitoring alerts you if it comes back.
