The following initscript can be used to start the socat tunnel on debian.
A file /etc/default/ox-push can be created to define parameters such as
DAEMON_ARGS.
 
After copying the script to /etc/init.d/ox-push do the following:
 
$ chmod 755 /etc/init.d/ox-push

Open-Xchange Mail Push

This package handles external notifications of new mail to send push requests to mobile devices.

Description

This Bundle is currently only able to cooperate with the mail notification functionality of cyrus-imapd, but this will change in a way, that future versions will be configurable on what kind of notification protocol is required.

At the moment, this bundle listens on the address and port as configured in /opt/open-xchange/etc/groupware/push_mailnotify.properties accepting UDP datagrams following the format as used in the cyrus notifyd: 

notifyd/notifyd.c:
method NUL class NUL priority NUL user NUL mailbox NUL nopt NUL N(option NUL) message NUL

and the only information which is currently being evaluated is the fourth one, the username.

Install on OX AppSuite

Debian GNU/Linux 11.0

Add the following entry to /etc/apt/sources.list.d/open-xchange.list if not already present: 

deb https://software.open-xchange.com/products/stable/DebianBullseye/ /
# if you have a valid maintenance subscription, please uncomment the 
# following and add the ldb account data to the url so that the most recent
# packages get installed
# deb https://[CUSTOMERID:PASSWORD]@software.open-xchange.com/products/stable/updates/DebianBullseye/ /

and run 

$ apt-get update
$ apt-get install open-xchange-push-mailnotify

Debian GNU/Linux 12.0

Add the following entry to /etc/apt/sources.list.d/open-xchange.list if not already present: 

deb https://software.open-xchange.com/products/stable/DebianBookworm/ /
# if you have a valid maintenance subscription, please uncomment the 
# following and add the ldb account data to the url so that the most recent
# packages get installed
# deb https://[CUSTOMERID:PASSWORD]@software.open-xchange.com/products/stable/updates/DebianBookworm/ /

and run 

$ apt-get update
$ apt-get install open-xchange-push-mailnotify


Install on OX App Suite

Debian GNU/Linux 11.0

Add the following entry to /etc/apt/sources.list.d/open-xchange.list if not already present: 

deb https://LDBACCOUNT:LDBPASSWD@software.open-xchange.com/products/appsuite/stable/backend//DebianBullseye/ /

and run 

$ apt-get update
$ apt-get install open-xchange-push-mailnotify

Debian GNU/Linux 12.0

Add the following entry to /etc/apt/sources.list.d/open-xchange.list if not already present: 

deb https://LDBACCOUNT:LDBPASSWD@software.open-xchange.com/products/appsuite/stable/backend//DebianBookworm/ /

and run 

$ apt-get update
$ apt-get install open-xchange-push-mailnotify


Configuration

On the server running cyrus, add the following to /etc/imapd.conf: 

mailnotifier: log

In /etc/cyrus.conf take care, that cyrus own notifyd is NOT in use. If it is not commented, either do that or remove it completely.

Example:

Note: The path to the socket in this example is valid for Redhat Enterprise Linux. On Debian it is /var/lib/cyrus/socket/notify. It might be different on your installation. Please check the default in /etc/imapd.conf on your system. 

 # this is only necessary if using notifications
 #  notify       cmd="notifyd" listen="/var/lib/imap/socket/notify" proto="udp" prefork=1

Install the program socat. Socat is a Multipurpose relay (see http://www.dest-unreach.org/socat/) which must be used to relay the udb datagrams from the unix domain socket to the open-xchange push bundle.

To redirect the notifications to the open-xchange server, socat must be started like this: 

socat -u -4 UNIX-RECV:/var/lib/imap/socket/notify,unlink-early,perm-early=777,type=2 \
         UDP-SENDTO:<YOUROXIP>:<YOURPUSHPORT>

To debug whether cyrus sends messages, you might want to add debugging to socat: 

socat -d -d -d -D -v -u -4 UNIX-RECV:/var/lib/imap/socket/notify,unlink-early,perm-early=777,type=2 \
         UDP-SENDTO:<YOUROXIP>:<YOURPUSHPORT>

Example Initscript for Debian

The following initscript can be used to start the socat tunnel on debian. A file /etc/default/ox-push can be created to define parameters such as DAEMON_ARGS.

After copying the script to /etc/init.d/ox-push do the following: 

$ chmod 755 /etc/init.d/ox-push
$ update-rc.d ox-push defaults
