I'd like to know how its possible if there isn't installed exim4 on my system, please look at my image:



Thanks for the answer!

there isn't installed exim4 on my system

Are you sure?

Code: Select all

aptitude search '?narrow(?installed, exim4)'

Thanks for the quick reply. I meant when I tried to run this command:

sudo apt-get purge exim4

the system answered this package is not available so it remove is not possible.

But after running your command I found exim4-base exim4-config and exim4-daemon-light are available. So I need to remove them all too, thank you.

UPDATE:

Originally my problem is I would like to use psad without exim4 on my system but I can't reinstall psad with this option yet. Any suggestions?

Install any one of these packages to satisfy the mail-transport-agent dependency (which is an accepted alternative to the default-mta dependency that pulls in exim4-daemon-light):

https://packages.debian.org/buster/mail-transport-agent

EDIT: or keep exim installed and just disable the relevant services:

Code: Select all

systemctl --all | grep exim
systemctl disable $unit # replace "$unit" with the name(s) of the unit file(s) returned by the first command

Good ideas, thanks for your help!

You're welcome. Please edit the title of the thread (in your first post) and prepend [SOLVED] to help others who encounter this issue. A more descriptive title would also help.

The "disable" option doesn't stop a service immediately, to do that you need to either pass the "--now" switch or use the "stop" option. Read the systemctl man page — you really shouldn't run commands unless you understand exactly what they do.

If you don't need MTA-specific tasks, such as queuing, etc. and you just want to be able to send e-mails via a mail relay, I can recommend nullmailer.

The configuration is extremely easy, and it works as it should.
