I have been trying to get iOS Mail Push Notifications working. The first step was getting the expired certificate renewed.. After much work, that got done. But Push still wasn't working. I read here:

that I would have to ad port 2195 to TCP in CSF which I did, for both IN and OUT. But that hasn't helped. Is it possible there is another CSF configuration preventing Push Notifications?
