    @adivinho Is it mandatory to specify below two lines in grafana.ini. Because we are restricted and cannot generate any App Passwords. So, we cannot specify our Account details Directly. Can you please let me know would it work if we do not specify below two parameters.

    -e GF_SMTP_USER=<gmail username> \

    -e GF_SMTP_PASSWORD=<gmail password> \

    gmail requires some sort of authentication to relay email...if you can't get a role account, can't specify an app password than I'm not sure what other avenues are available. Do you have an internal SMTP server you can point your PMM instance to that doesn't require SMTP auth?

    @steve.hoffman yep. Let me check and see if it works.
