Problem with z-push is the way it handles meeting invitations - I discovered several problems with this: a) outgoing invites are not sent correctly (empty mail instead of ics attachment)b) incoming invites can't be accepted or declined (no RSVP buttons) There is a fork of z-push called Z-Push-Contrib on github where these stuff may be resolved in the future. In addition I discovered similar problems with sogo when using IMAP/calDAV combo. There seems to be some problems with iOS as well.

But I have another mailbox on MS Exchange server with Push enables and it nevers falls in endless loop. Therefore there must be something wrong with SOGo. Indeed. Push *should* work without impact on battery life, unfortunately not with SOGo ATM. 2) It was me who wrote about NAT. Now after many days of testing and many other combinations of SOGo parameters I must say the problem with endless loop is much more complex and unpredictable. It is just my personal empirical observation but definitely there is no direct relation between parameters and endless loop. Sometimes it falls to endless loop even after another action. For example after adding new entry to calendar on my laptop. I think I found following workaround...if I switch off task syncing on my iPhone for a while and again switch it on, the communication "heartbeat" will slow down and goes back to the limits according SOGo parameters. In my opinion there must be something wrong in sogo deamon. Meaning how sogo server handles changes and pushing them to EAS device. Nevertheless even the setup of my iPhone has an impact on it. Maybe...just my hypothesis...when I re-enable syncing of tasks...SOGo will do some kind of initial sync which synchronize correct way my iPhone. After this action it works for a while. Ah, thanks. 3) EAS brings very significant advantage to common users...easy setup.And nothing more than that I am afraid. From any other perspective and performance impact on client/server IMAP/CalDAV/CardDAV combo is far superior, at least for the time being. RegardsMartin. It isn't just the "simple setup" that makes it useful for certain users. In our case we can only have port 80 and 443 open to the internet. So IMAP is a no go. Activesync is a great solution for this. However I have never had good luck with the sogo implementation of it. We have been using zpush on a separate server successfully since nearly the beginning of using sogo though. I just wish I could get it to work with calendars and contacts easily. Email is flawless. -- [email protected] https://inverse.ca/sogo/lists
