Answer 1

Enter your SMTP server information in the "E-mail Notification" section of the global configuration instead of the " Extended Email Notification Plugin" section.

You're using the E-Mail notification "post-build" step. That is unrelated to the "Extended Email Notification Plugin", so it does not use the corresponding settings either.

Answer 2

Did you enable "not secure app" connections in your Google Settings? It surely be mandatory to use the google account in third apps.
