I have configured items related to SMTP service in the app.yml configuration file, but I still cannot receive the activation email correctly

Thanks for your help. Now I have successfully activated my administrator account through the command line, but I still cannot send emails through SMTP. I have successfully sent test emails through Telnet on the server, so I think there are some configuration items in app.yml that I am not clear about, which causes my problems
