Z-push and push on mobiles

Good evening,

I’m experimenting with Z-Push push tech. What does it require?. Does the IMAP server need to support some feature?. Do you need any apple license or Google license for sending push notifications?.

Best regards,

Hi @egoitzau,
what exactly is your question? You can find lot’s of infos here:
best regards

nope, no need currently have postfix with dovecot working with ZPUSH and NGINX

HI AnotherAndy, Killmasta93,

I see I’ll read the url…

By the way killmasta93, could you know if idle or similar is needed in the imap server?.

Best regards,

By the way AnotherAndy, have not seen the answer to my question in the provided url…


-> here you can see the different packages, for example z-push-backend-carddav or z-push-backend-imap
But you’re right - I also can’t find a list of supported servers :-(

@AnotherAndy yes but I was wondering which Push capabilities Z-push provides and if some special requirement was needed for that?..

Best regards,

Hi egoitzau,

the IMAP backend is mostly a community contribution, so I don’t know all the exact details how it works.

The IMAP backend uses PHP’s imap_* functions to get data from the IMAP server. As far as I know it doesn’t require any special features of the IMAP server.

You could check the ChangesSink function in imap.php to get the idea how Z-Push gets new messages.


Thanks a lot Manfred
