Is it possible to enable push notifications for iOS/macOS mail clients on a stock dovecot?

[Gerben Wierda]

This requires the ongoing use of macOS Server (as does the patch that is part of the MacPorts port of dovecot2). The issue then is: how do you keep getting certificates for push mail if mail services have been removed from macOS Server? I can configure this today but on Oct 20, my apns certificate expires. Then what?

Now, that certificate needs to be renewed yearly by Server.app and imported by hand etc. At some point this will stop working (apart from that you need to keep an old macOS Server around to renew)
