Earthlink Email is not Delivered

Users with an Earthlink email address may not receive email messages generated from this website. This is because Earthlink incorrectly rejects the email from our server indicating there is a configuration error.

Our server is properly configured and verified by the other email services on the Internet, so the problem lies with Earthlink. Earthlink has been unresponsive to our requests and the requests of its users to resolve this issue.

To circumvent the issue, we recommend that Earthlink users create a free email account on gmail or another free service. Have that account forward email to their Earthlink mailbox.

If you create a new email address, you need to update your email address on this website. Use the menu "My Account", "My Account Settings".
