SMTP host

                 host or ip address of your smtp server (example: smtp.gmail.com)

                 FYI: it seems smtp.gmail.com is usable only by Google G Suite subscribers.
            
Port
the default port is 25, but some smtp server use a custom port (example: 587)
 
                 Use Secured Connection
            
 checked it only if the smtp server needs a secured connection (ssl, tsl)
 
                 Use authentication
            
 most of smtp servers need an authentication (login/password). Check it if required
Login
required if 'Use authentication' is checked (ex: account or account@foo.com)
Password
required if 'Use authentication' is checked

                Email from
            
the sender's email address (example: account@gmail.com)

                Email to
            
very important : the test mail will be sent to this address (ex: account@gmail.com)
