/etc/networks has:
loopback        127.0.0.0

Not sure how to check this in detail, I never had to do this in 15 years 
of using Debian.

Interesting:

sonata at 23:17:~$ sudo /etc/init.d/exim4 stop
[ ok ] Stopping exim4 (via systemctl): exim4.service.
sonata at 23:17:~$ sudo netstat -napt | grep :25
tcp        0      0 127.0.0.1:25            0.0.0.0:* 
LISTEN      8769/exim4

Although I stop it, it's still running...?

root      8769     1  0 23:16 ?        00:00:00 /usr/sbin/exim4 -bd -q30m

So, something else also started it?

Looks like it's already started then, outside of systemd... what could 
it be?

As I said before, even though it gives that error, it is still able to 
send the e-mail that the paniclog has grown. I guess that can be 
explained by the fact that there was already an exim4 running indeed.

This is what systemd logging says about my boot today:

$ sudo journalctl --unit=exim4.service
-- Logs begin at vr 2016-01-15 19:02:54 CET, end at vr 2016-01-15

Agent...

/var/log/exim4/paniclog has non-zero size, mail system
jan 15 19:02:56 sonata systemd[1]: Started LSB: exim Mail Transport Agent.

So, it still says it started the service.

Is it possible this has to do with the automatic removal of 'ifupdown'? 
It started when installing/upgrading several packages as listed in my 
original report.

Do you really think that's a helpful remark?
