Why can't I remove a PBL IP with a freemail address? (Gmail, Hotmail, etc.)
The PBL removal system does not process removal requests that come from free email accounts such as Gmail.com, Hotmail.com, Yahoo.com, or any other free email domains. Any removals that are made using free email addresses are automatically invalidated by the PBL removal system security checks.

You must use your real address at your own domain to request PBL removals.

Since the only legitimate reason for removing an IP address from the PBL is when there is a legitimate mail server hosted on the IP address, only operators of legitimate mail servers should remove IPs from the PBL (and then strictly only the IP address of the mail server they operate). Therefore the self-service removal process assumes that the person requesting the removal of an IP is the operator of a mail server hosted at the IP address. That person would normally use a 'postmaster' address and not 'anon1234@gmail.com'.

All legitimate mail servers have proper hostnames and the server operator usually has a role address (such as "postmaster") which is used to receive operational communications. The operator of a legitimate mail server does not need to use a freemail address for operational communications. For this reason we treat removals requests from freemail addresses as being suspicious and do not process them.
