How to get removed from ImproWare Worm RBL

ImproWare Worm RBL removes entries automatically once the activity stops. There is no form to speed it up.

  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 No removal request is needed: the entry expires automatically once the activity stops.
  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.
