dovecot - Jun 2018 - Looking into a solution for Caldav (and possibly carddav) support

We have an existing Dovecot/Postfix/Roundcube email solution, which I 
was hoping to add Caldav (and carddav?) support to, with the goal of 3rd 
party email clients being able to keep contacts and calendars in sync 
(as well as having the same information in roundcube)

In doing research, I came across traces of it being considered for 
Dovecot at one time 
(https://www.dovecot.org/list/dovecot/2015-September/101996.html), and I 
was wondering where this went.


Specifically, 
https://www.dovecot.org/list/dovecot/2015-September/101997.html seemed 
to hint that metadata support was a prerequisite for this (mainstream as 
of the email), and I was wondering if this meant there was potentially a 
solution built on top of this.


Thank you

Hello,

The metadata support in dovecot is now quite stable ( at least i didn't
encountered problems on my servers )

But the metadata is only about marking the folders ( you can mark a
folder as "calendar" or "contact").

caldav/carddav are based on webdav protocol, so normally you need an web
server to publish them.

In kolab there is iRony as web application.

I can confirm you can use dovecot ( instead of cyrus) but is not trivial
and I didn't know much about the compatibility for shared calendars.

The requests I had are mainly regarding contacts ( it depends on the
type of organization you serve) .

So, it is possible but it is not about dovecot alone but it's an entire
ecosystem ( and that's normal). I think implementing webdav directly in
dovecot is somehow reinventing the wheel..

Cyrus IMAPd provides exactly that, easily ;-)

Hi,

It sounds as if you want to be looking at sogo.nu:

https://sogo.nu/

It re-uses your imap/mail setup, and implements caldav/carddav, and also 
ActiveSync to interact with the same contacts/calendars.

Take a look: It's modern and very well-maintained, plus light-weight.
