Check Setting up mail dispatching in Linux
So you need to configure the docker container to at least one MTA is working as well.
i can use the terminal of check mk inside the dockercontainer but seems i cant find the smtp settings been looking under /etc but so far no luck
Well you need to be familiar with Linux OS and how to setup a MTA for example, Postfix, Qmail, Exim, Sendmail or Nullmailer.
As you figured out in CheckMK you only setup a email address.
For Postfix check Basic Postfix Configuration
ok thanks for the hint, but what i did do is enable smtp on my synology nas and installed synologymailplus server or isnt that the same?
Well but your Docker Container (Linux Instance) did not know who to contact to send mails to.
Therefor you need an MTA here as well, which take care of local mails and send them accordingly to your MailServer.
ok thanks, i wil try install postfix on the local checkmk container?
Based on your screenshot postfix is already installed, you need to configure it accordingly.
May be a solution for you: Configure Postfix to Send Email Using External SMTP Servers | Linode Docs
thank u i got it to work, by following the guide thanks alot!
