I?ve been hacking on a personal side project to support native iOS Push Email in Dovecot. This is specifically for people who are migrating their mail away from OS X Server while keeping their existing Push Email functionality. Native Push Email has some great advantages: it speeds up email notifications (usually within seconds of being handled by dovecot-lda) and it improves battery life since the native notifications flow over a single highly optimized connection to Apple?s infrastructure. Although this is at version 0.1, it is working pretty well for me and I am looking for some additional testers that are interested. Please note that it is not possible to use this project without legally running a copy of OS X Server. You can purchase OS X Server on the Mac App Store or download it for free if you are a registered Mac or iOS developer. This feature is enabled by two projects: https://github.com/st3fan/dovecot-xaps-plugin <https://github.com/st3fan/dovecot-xaps-plugin> https://github.com/st3fan/dovecot-xaps-daemon <https://github.com/st3fan/dovecot-xaps-daemon> Both projects contain a README that describes how to get things going. I have only developed and tested on Ubuntu 12.04.5 so ideally you run the same version if you are interested in playing with this project. You will need to compile some code and not be afraid of a little admin work. I am also interested in a code review. The Dovecot plugin API is barely documented and I had to guess a lot of things by looking at other plugins. An extra pair of eyes specifically on that code would be awesome. Also from a security perspective. Please file bugs! S.
This is interesting; I'm not sure if I got that right from scanning the READMEs. Do I really need to have a working OSX-server setup which I then do migrate away from? What makes this certificate that special such that I only can export it from the existing server setup? -M Am 05.09.2014 um 03:35 schrieb Stefan Arentz <stefan at arentz.ca>:> I?ve been hacking on a personal side project to support native iOS Push Email in Dovecot.

Would you mind explaining *why* the above is required? Is this just a temporary limitation of some kind?

The only note is to copy the plugins file (imap_xaps_plugin.so and xaps_plugin.so) manually in /usr/lib/dovecot/. I hope you will release a version with the ability to run in background the daemon. Thanks

I had been planning to look into this as well, but never had much time. Some comments from a quick look: - xaps_str_append_quoted() doesn't quote CR/LF/TABs. Of course those shouldn't normally exist in any of the fields, but older Dovecot versions would have allowed creating folder names with them. Using the str_append_tabescaped() would escape them as well, although then you'd have to implement the unescaping also with Python. - ideally the communication between Dovecot and xaps-daemon would be done asynchronously, but as a quick change you could also use i_stream_create_fd() + i_stream_read_next_line() instead of the strtok_r call. Oh and in internal Dovecot protocols it has always used LF, not CRLF, which would also make it a bit easier to handle. - in xaps_notify() especially async IO would be much better to avoid latency. It's also easier to do than in init, since it wouldn't really even need to wait for the response. Even without async IO does it really even need to read the answer from the server? - also to avoid bursts of notifications in some situations, you could use timeout_add(NOTIFY_DELAY_MSECS, ...) and have the timeout function send the notification. The delay being for example 0,5 seconds or maybe configurable. BTW. We could have some other Dovecot plugins that need to be developed if you want more (paid) work. :) We need to hire more developers to reduce my work load..
