Zimbra?Carbonio? What are the supported backends?

[BloodyIron]

I can't for the life of me tell from the documentation, reliably, what backends the latest Z-Push versions can work with.

Since Zimbra OSE has effectively been EOL'd, I'm evaluating Carbino to eventually migrate to. But I need EAS (Exchange ActiveSync) and Z-Push has served me well with Zimbra OSE for years for EAS, so I probably will try Z-Push for Carbino too.

So, can we get this fleshed out in the documentation? Not only outlining which ecosystems Z-Push can work with out of the box, but also any specific steps to Carbino or other ecosystems, not just for Zimbra (as much as I love Zimbra, sad to see it go, but I can't tolerate no security updates for my E-Mail system).

Thanks!

Probably best to ask at the Zimbra Backend project https://sourceforge.net/p/zimbrabackend/discussion/998911/

As far as I know both Zimbra 9 & 10 built from source will be supported in the next Zimbra backend release. No idea on Carbonio.

The Github wiki is open to edits, if you find out the above and want to add it in.

Edit: Carbonio spelling

Hi! As far as I know, Carbonio is based on Zimbra, and also uses z-push in paid licenses for activesync functionality. However, in case of any problems, nothing will prevent you from switching to the imap backend.

IAMP is not even close to an acceptable alternative to EAS (Exchange ActiveSync). It's unreliable and is lacking features in comparison. Hence asking on the github repo for a tool that provides EAS.

Carbonio is a fork of Zimbra yes, but I cannot determine how they provide EAS in their paid version, so I don't know where you found evidence they use z-push for that. Or are you just speculating?

If z-push is already capable of providing EAS for Carbonio, that would be great, but that's really why I raised this thread. I wanted to know if z-push can already work with Carbonio for EAS serving.

And no, I'm not going back to IMAP. That's a horrible recommendation.

The devs/team behind Zimbra are not the same as Carbonio devs/team. Carbonio is a fork, so asking the Zimbra folks would be a fool's errand.

The Zimbra Backend is not maintained by Zimbra (though Zimbra might have their own version of it as well).

I would encourage you to reach out to the Zimbra Backend project on Sourceforge and ask them directly what they support.

A quick google search reveals that it has worked for people 2 years ago

https://github.com/imanudin11/zimbra-zpush

The latest releases of Carbonio might be waiting on the next release of the Zimbra Backend, the same as the latest Zimbra.

Instead of directing you to ask the Zimbra Backend project again, I have asked for you.

Response from Zimbra Backend

I have no idea, and no way to test.

I have heard Carbonio is a fork of zimbra FOSS. If they only changed the skins/etc but not the underlying SOAP infrastructure then it should work. If they made more substantial changes under the covers then your guess is as good as mine.

I'll leave it up to you or someone else to test if it works, but I would say that officially it is not supported as the Zimbra Backend project isn't able to test.

If you find out feel free to update the wiki or start a discussion.
