ActiveSync / Push Notifications for Cloudron Mailserver

[Mallewax]

I understand from other posts that this had been looked at before,

https://git.cloudron.io/cloudron/sogo-app/-/issues/4

but it did not work/install at the time. But now there are Ubuntu 18.04 LTS packages available.

https://repo.z-hub.io/z-push:/final/Ubuntu_18.04/

It would surely be nice if we could add push notifications to the Cloudron Mail Server instance.

I had to look up the difference between IMAP IDLE and ActiveSync. Per https://www.aspnix.com/kb/sales-kb/imap-idle-vs-activesync/, "While IMAP IDLE provides real-time notifications to your client, it differs from ActiveSync in many ways. IMAP IDLE is an extension of the IMAP protocol (as described here) and IMAP being a message protocol, it handles only email. ActiveSync (as described here) handles email, calendar, contacts, notes and tasks, and syncs them across all of your clients (that support ActiveSync, including devices)."

@girish I also note that it adds:

"IMAP IDLE can also only generally receive notifications for the folder you currently have selected / viewing. ActiveSync does not have this limitation and receives real-time notifications for all folders."
