I’m a fan of push mail. Not having to pull your mail manually or at a given interval is a huge advantage. That’s why I use Z-Push on my private mail server.
Lately I’ve been playing for the second time with the Autodiscovery protocol. Found a neaty little PHP script that does all the magic for me and it seems to work on both iOS 6 and Android 4.2.2. Great! But there was one little problem. Autodiscovery always put the whole email adress as the username. I don’t allow that in my mail configuration. So what now? I couldn’t find a way to persuade Autodiscovery to put the right username as username and I found that this would be too complicated as you can have aliases for mail, so the login part would be wrong anyway.
Fortunately I already use the virtuser_file plugin in RoundCube Mail. Porting it to Z-Push was a piece of cake. Here’s the patch if you’re interested:

This works with Z-Push 2.0.7. My virtual map file looks like this:
email@domain.tld real_username1 email2@anotherdomain.tld real_username1 test@domain.tld real_username2 etc...
If you like it, you can copy&paste the patch or download it from here
Cheers!
