Earthlink help needed


I'm also having an issue with mail delivery to earthlink. It seems some of the messages to earthlink are not reaching the inbox post the initial acceptance. Can an earthlink administrator confirm off-list if this is something the client can control? The few that I have examples of swear they never receive the message but our logs show it was accepted for delivery.
