Overview
fedmsg-relay is a service which binds to two ports, listens for messages on one and emits them on the other. fedmsg-logger(1) requires that an instance of fedmsg-relay be running somewhere and that it's inbound address be listed in the config as one of the entries in relay_inbound.
fedmsg-relay becomes a necessity for ephemeral senders, that cannot bind consistently to and serve message from a persistent port.
