I'm trying to setup an alert with action to send me an email.
I have been going through the forum and googled, but am not able to solve the error message I am receiving in the NT log. This occurs when I try to send a test email (from the setup screen).
The error message using port 587:
There was an error sending a mail message: The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.0 Authentication Required. Learn more at
The error message using port 465 (as this seems to be the correct port with SSL):
There was an error sending a mail message: Syntax error, command unrecognized. The server response was:
The log:
My setup:
This Google account doesn't have 2-step-verification, so I understood that I wouldn't need to create an app password.
Could you please have a look at this and guide me through the process?
Thank you in advance
Dennis
