Earlier this week I was at MAAWG and one of the Earthlink postmaster folks stopped me to tell me that Earthlink was now accepting non-ISP applications to their Feedback Loop.
In order to apply for the Earthlink FBL send an email to fblrequest@abuse.earthlink.net with the IP addresses and the FBL email address.
