Earthlink

Delivering to
Earthlink handles mail for the earthlink.net, mindspring.com and peoplepc.com domains. They were one of the primary dialup ISPs in the early days of the Internet. They have since fallen behind other ISPs. They have partnered with a number of cable and broadband providers as well to provide email services for those customers. Earthlink does not publish  either connection or sending limits.

Postmaster pages
Earthlink does not provide a postmaster website.

Feedback loop
Earthlink does provide a feedbackloop, and early in 2013 opened the FBL to all providers, including ESPs. Signup is through email only. Send email to fblrequest@abuse.earthlink.net.

From Earthlink folks the email should:
 * Mention FBL or feedback loop in your subject to make sure it makes it through the filters.
 * Be sent in plain text only, and IPs in just a plain list if singles or in a plain list of valid CIDR ranges as appropriate.

The email itself should have


 * 1) The IP address(es) that you wish to receive reports on
 * 2) Email address you want ARF reports sent to
 * 3) Administrative contact email address
 * 4) Company name and information (address, phone number)

Certification Services

Support for Senders
Earthlink does not provide much support for senders. If you are blocked by Earthlink, send mail to blockedbyearthlink@abuse.earthlink.net with the blocked IP in the subject line.

Known spamfilters
Earthlink was an early adopter of Brightmail filters. They also run an extensive internal blocklist.
