For example, when sending a selected message to SimplePush, currently I send:

{"alias":["test@test.com"],"message":{},"simple-push":{"mail":"version=1"}}

and the only logging on the server i see is:

10:38:10,976 INFO [org.jboss.aerogear.connectivity.rest.sender.PushNotificationSenderEndpoint] (http--0.0.0.0-8080-5) Message submitted to PushNetworks

Would be nice to have more info about what was sent and where to track down messages that don't go through.
