Agree - native functionality means its part of the UI, not a manual configuration. I don't believe there is even a default appender. You have to build it from scratch.
No, native functionality means that it is officially supported! Thare are many things you need to do by altering config files. I understand that it makessetup probably little bit easier as you do everything in single console.
Re appender method: configuration with xml is down to putting recipients email address/cc, smtp server name or ip and credentials if required. The same info you will have to provide in qmc. Whole setup with xml takes 30 seconds so please dont judge this solution unless you have tried it.
On another note-notifications in qmc are already there in June 2019 TP - so hapy days
It all depends on your SMTP server settings. If your smtp does not require authentication and just listens say on port 25 then you dont need a password, nor username.
Below whole, XML just populate it with your smtp server, "from","to", you can add CC (details to documentation are on help.qlik.com )
