I have issues with fail2ban and exim4 services aren’t starting or simlar to this !

Regarding Exim:

Are there log files in /var/log/exim4/?

ls -la /var/log/exim4/

Is there something interesting in paniclog and/or mainlog?

Regarding fail2ban:

You didn’t show all the lines, the output is cut off but seems it is failing to start because the exim issue (can’t find exim’s logs).

sahsanu · December 18, 2023, 7:57pm

I can’t see a mainlog file, mainlog.1 is the yesterday’s log.

Do you have free space?

Yes sir !

That’s all what it is there is no mainlog “”

sahsanu · December 18, 2023, 8:07pm

Try to restart exim and show the status again:

systemctl restart exim4
systemctl status exim4

Show the contents of /etc/exim4/ dir:

ls -la /etc/exim4/

And show the exim installed packages:

dpkg -l | grep -i exim

sahsanu · December 18, 2023, 8:15pm

Did you reinstall exim or modified the conf in some way? I’m asking because conf has been modified two hours ago.

savage · December 18, 2023, 8:16pm

Yeah I just replaced conf file with the .back file since it wasn’t working I tried to do some google and stuff and in the forum aswell I found no luck so I am here now !

sahsanu · December 18, 2023, 8:22pm

Here the main problem is that we don’t have a log and don’t know the reason exim is not starting correctly.

Show me the output of:

cat /etc/exim4/update-exim4.conf.conf

savage · December 18, 2023, 8:31pm

Sure here:

https://termbin.com/tkwa

sahsanu · December 18, 2023, 8:43pm

That conf file is correct.

Just in case, show the output of journalctl:

journalctl -xa --no-pager --since=yesterday --until=now -u exim4

Also the exim4 conf:

cat /etc/exim4/exim4.conf.template

And also the services that are listening in your server:

lsof -Pn +c0 -i -sTCP:LISTEN

savage · December 18, 2023, 8:50pm

sahsanu · December 18, 2023, 9:17pm

Your exim4 conf is not using dovecot_virtual_delivery.

I’ve modfied your exim conf, replace it and try again:

cd /etc/exim4/
mv exim4.conf.template exim4.conf.template.backup_2023-12-18
curl https://termbin.com/xe5v -o exim4.conf.template
systemctl restart exim4
systemctl status exim4

The results the hostname isn’t na.na.na btw

sahsanu · December 18, 2023, 9:45pm

Lets try this:

systemctl add-wants multi-user.target exim4.service
systemctl start exim4
systemctl status exim4

If that doesn’t work:

/etc/init.d/exim4 start
lsof -Pn +c0 -i -sTCP:LISTEN | grep -i exim

If that doesn’t work too, reboot the server and if that doesn’t work, then…

savage · December 18, 2023, 9:46pm

Failed to add dependency: Unit /run/systemd/generator.late/exim4.service is transient or generated.

No out put out of:

lsof -Pn +c0 -i -sTCP:LISTEN | grep -i exim

well reboot then see what happend, and still no luck !

sahsanu · December 18, 2023, 10:01pm

I’m sorry but I’m running out of ideas

Let’s debug the start just in case we can see something…

bash -x /etc/init.d/exim4 start

savage · December 18, 2023, 10:08pm

root@na7:/etc/exim4# bash -x /etc/init.d/exim4 start
+ set -e
+ test -x /usr/lib/exim4/exim4
+ exit 0

savage · December 18, 2023, 10:21pm

Solved ! by doing this:

apt remove --purge exim4 exim4-config

and reinstalling it:

apt install exim4
