When trying to create a Notification channel and send a test message, I am getting the following error:

Failed to send the test message - unknown error

Configuration:

Hey @Phandora

SMTP access to Gmail is disabled by default i beieve. To permit the application to send emails using your Gmail account follow these steps help fix my issue a while back.

Open the link: https://myaccount.google.com/security?pli=1#connectedapps

In the Security setting, set ‘Allow less secure apps’ to ON.

I personally use either Postfix or sendmail on my linux device. Send mail locally wil use port 25, 127.0.0.1.

Maybe this might help
