Single IP removal for outbound email server administrators

Single IP removal for outbound email server administrators

It is quick and easy for mail server administrators to exclude their static IP address from a PBL Zone Listing.

In the Blocklist Removal Center, insert the IP in question into the “Enter an IP Address” field, and click “Lookup”. This will provide a web form for self-removal. Fill in the form and follow the instructions, and then wait approximately 15 minutes to allow for DNS propagation.

Only IP addresses that meet all of the following criteria should be removed:

The IP must be:

  • Static – not dynamic!
  • An outbound mail server
  • Configured with appropriate Reverse DNS
  • Assigned to the individual or company performing the removal


Only single IP addresses that are assigned to mail servers should be removed; IPs that do not run an outbound email server are not appropriate for removal.

NOTE: If it is necessary to remove multiple IPs, the ISP that is assigned those IPs should request the removals. Individuals that remove many IPs may find their removal access revoked, and their removals reversed.

  • End-user single-IP exclusions from PBL Zone Listings expire after one year, and will be immediately reversed if spam is detected from them.
  • ISPs with PBL Accounts may select shorter expiration periods for exclusions, and may add or remove lists of many such single-IP exclusions.
