Does anyone happen to know the current status of push email in the linux world? From my searching at the moment I have seen Z-push http://www.ifusio.com/blog/setup-your-own-push-mail-server-with-z-push-on-debian-linux and https://peterkieser.com/2011/03/25/androids-k-9-mail-battery-life-and-dovecots-push-imap/

Are there other solutions? Does anyone have any experiences with these? They're somewhat different in that Z-push seems to work in conjunction with an existing imap server?

Some time ago I did manage to compile and build Dovecot 2 (since only Dovecot 1 was available in the Ubuntu repos at the time), it would have been a real fluke because I had no idea what I was doing but it seemed to work well with my mobile phone, that said, I can't say for sure that it was pushing, but it seemed like it.

Anyway, I'm here again and looking to set up a mail server. I'm hoping to do a better of a job this time around with virtual users and such.

Without installing ispconfig3 (or something similar), does anyone have any recent email server tutorials (that cover all aspects MTA, MDA...) that can supply push email on a Ubuntu 12.04 server?

(I'm probably of slightly above newb status, but not far)

Thanks a bunch
