[SOLVED] I don't get email notifications working.

I'm trying to set up the email notification. I have configured my from address in datacenter\options\email from address. My mail server accepts messages on port 25. With telnet I can access this server / port. Only no messages are coming in. I also tried to set my mailserver at relayhost in /etc/postfix/main.cf. But this makes no difference
Also I don't get a /var/log/mail.log file.

service postfix status give:
● postfix.service - Postfix Mail Transport Agent
Loaded: loaded (/lib/systemd/system/postfix.service; enabled; preset: enabled)
Active: active (exited) since Sun 2023-08-13 17:07:55 CEST; 33min ago
Docs: man: postfix(1)

Main PID: 1089 (code=exited, status=0/SUCCESS)
CPU: 1ms

Aug 13 17:07:55 VWD001n systemd[1]: Starting postfix.service - Postfix Mail Transpor>
Aug 13 17:07:55 VWD001n systemd[1]: Finished postfix.service - Postfix Mail Transpor>

Do I need to configure anything additional to activate email in proxmox?

Normaly not. Do an test. Open 2 terminals. In one terminal you open the logs:

journalctl -f

In the other termnal, you send an testmail:

sendmail blabla@whatever.xx

your message

In the logs you should see an process/output whether the mail was sent successfully.
Thanks, it works now. Because I could now see a log with journalctl -f it turned out that myhostname was not set up correctly
