Alerts and Reports not working after updating SMTP credentials about superset HOT 3 CLOSED

Hey @mayanklalwani! I'm here to help you with any bugs, questions, or contributions. Let's tackle this issue together!

The "Authentication Credentials Invalid" error after changing the SMTP credentials in the superset_config.py file, despite the credentials being correct when tested separately, could be due to the EMAIL_NOTIFICATIONS setting being set to False. This setting needs to be True to enable email notifications.

Here is the relevant part of the configuration:

# smtp server configuration
EMAIL_NOTIFICATIONS = False  # all the emails are sent using dryrun
SMTP_HOST = "localhost"
SMTP_STARTTLS = True
SMTP_SSL = False
SMTP_USER = "superset"
SMTP_PORT = 25
SMTP_PASSWORD = "superset"
SMTP_MAIL_FROM = "[email protected]"

To resolve the issue, change EMAIL_NOTIFICATIONS to True:

EMAIL_NOTIFICATIONS = True

This change will enable email notifications and should resolve the "Authentication Credentials Invalid" error if the SMTP credentials are correct ^[1].

Sorry for the dumb tech support "is it plugged in?" question, but did you restart Superset after changing the config?

from superset.

Also these variables can be set in multiple places - a .env file, superset_config.py, config.py, superset_config_docker.py. If the old ones remain in a different file that is getting loaded after where you set them, that could cause this problem.

We can probably convert this to a discussion as it seems more like a config settings issue, not a bug in the Superset codebase.
