Reproduce the failure with the documented Docker commands and the HertzBeat notification path: add a recipient, enter the email details, and run the test. Start from the reported smtp.qq.com port 587 connection error and compare the SMTP settings with the container's behavior. Done means the email notification test succeeds without the SSLException.
