SendXMPP mail forward on Debian Jessie

To have a more comfortable way of receiving messages by my servers, I wanted all my root E-Mails to be forwarded to my mobile via XMPP. I only have a limited exim4 on my machine running, configured for local mail delivery only.

So what is the solution

1. Install sendxmpp

apt-get install sendxmpp

2. Create config file as “/etc/sendxmpp.conf”

@

as an example:

sendinguser@jabber.mydomain.com supersecretpassword! mydomain.com

3. Set the right permissions and owner

chmod 600 /etc/sendxmpp.conf
chown Debian-exim:Debian-exim /etc/sendxmpp.conf

4. Create a script to call sendxmpp as “/usr/sbin/mail2xmpp”. It might be that you could put this completely into the alias, however I decided to use the script.
Exchange with your receiving ID. “-t” enables the TLS connection for sending the message.

#!/bin/bash 
echo "$(cat)" | sendxmpp -t  -f /etc/sendxmpp.conf

5. Make script executable

chmod 755 /usr/sbin/mail2xmpp

6. Create the alias for the user, which E-Mails you want to forward in “/etc/aliases”

root: , |/usr/sbin/mail2xmpp

7. To activate pipe forwarding we have to create “/etc/exim4/exim4.conf.localmacros”

SYSTEM_ALIASES_PIPE_TRANSPORT = address_pipe

8. Run newaliases and restart exim4 for config to take effect

newaliases
service exim4 restart

Now you should be able to test if it works, by simply sending a local test E-Mail to user “root”.
