When running

systemctl restart crowdsec

I get

Job for crowdsec.service failed because the control process exited with error code.
See "systemctl status crowdsec.service" and "journalctl -xeu crowdsec.service" for details.

I tried to use none, single or double quotes to set the appropriate values in

/etc/crowdsec/notifications/email.yaml

Nothing helped.

Any reply would be greatly appreciated.
thx

seem your email.yaml is incorrect, it seems the contact addresses is a string when it needs to be an array of strings like:

wrong

receiver_emails: "myemail@domain.tld"

right

receiver_emails:
  - "myemail@domain.tld"

thx @iiAmLoz for taking time

This does it :slight_smile:

CrowdSec starts without errors.

But when testing it throws

cscli notifications test email_default

That error is stating the email setting are not working for connection timeout, ensure the settings you are using are correct such as hostname and port
