You can also set MDOsprey to nomail.  You will still be subscribed to the list, but won't receive any messages; Earthlink therefore won't bounce you.  You can keep up with MDOsprey by reading emails at the MDOsprey archive site, and you can still post when you want.  This is what I do.  By and large I haven't received emails from Osprey in many many years.  I believe that this email account is the fifth I've used to subscribe to MDOsprey during the ten-plus years I've been subscribed.
