Setting up email alerting using postfix

[leegreg77]

I have been trying to set up email alerts using a local smtp server by following this article https://sbcode.net/grafana/create-email-alert-notification-channel/
I have tested PostFix and I can send an email from Ubuntu Terminal and receive it to terminal, but every time I try to send the test email in Grafana I get a message saying the smtp section of the .ini file hasn’t been updated. I think I am getting further away from where I should be as I am trying different things. I currently have this.

What do I need to change to get this to work?

Remove the semi column ; and restart grafana
; means commented out hence the reason it is not working

Thanks for the reply I have changed the .ini file to this:

However I now get an error when I restart Grafana
