This z-push docker image is designed to work in lieu with the tvial/docker-mailserver (see tomav/docker-mailserver for further information.)
TIMEZONE: in the format ofEurope/ZurichIMAP_SERVER: your imap server address/ipIMAP_PORT: imap portSMTP_SERVER: smtp server address/ipSMTP_PORT: smtp portDEBUG: [0/1] disables/enables verbose logging.
For a quick guide, how to setup up your mobile device, have a look at the Zarafa-Homepage
If you need to change the default configuration, you can do so by placing a config.php and/or a imap.php into a folder which has to be mounted as a volume to /config/ inside the container.
Note: Those files just get appended to the container configuration files for now.
Example:
docker run -d -name z-push \
-v ./config:/config/ \
-e TIMEZONE=Europe/Zurich \
-e IMAP_SERVER=imap.yourdomain.tld \
-e IMAP_PORT=143 \
-e SMTP_SERVER=smtp.yourdomain.tld \
-e SMTP_PORT=465 \
-e DEBUG=1 \
17halbe/z-push`
The used configuration is being put out to the docker logs upon container start, and can be read by docker logs <your_container_name>
Here are the settings used at the time of writing:

* This feature is supported only by certain devices, like iPhones.
* Check the compatibility list for supported devices:
* http://z-push.org/compatibility
*
* To synchronize a folder, add a section setting all parameters as below:
* store: the ressource where the folder is located.
* Kopano users use 'SYSTEM' for the 'Public Folder'
* folderid: folder id of the folder to be synchronized
* name: name to be displayed on the mobile device

* SYNC_FOLDER_TYPE_USER_APPOINTMENT
* SYNC_FOLDER_TYPE_USER_TASK
* SYNC_FOLDER_TYPE_USER_MAIL
* SYNC_FOLDER_TYPE_USER_NOTE

* Additional notes:
* - on Kopano systems use backend/kopano/listfolders.php script to get a list
* of available folders
*
* - all Z-Push users must have at least reading permissions so the configured
* folders can be synchronized to the mobile. Else they are ignored.
*
* - this feature is only partly suitable for multi-tenancy environments,
* as ALL users from ALL tenents need access to the configured store & folder.
* When configuring a public folder, this will cause problems, as each user has
* a different public folder in his tenant, so the folder are not available.
* - changing this configuration could cause HIGH LOAD on the system, as all
* connected devices will be updated and load the data contained in the
* added/modified folders.
