When you create a new site or update an existing site, you can enable SMTP email server authentication using the properties in Site Settings node properties.
Email::User Name - The name of the user needed to provide credentials for SMTP server authentication when sending emails.
Email::Password - The password of the user needed to provide credentials for SMTP server authentication when sending emails.
Email::SMTPPort - The port used by the email server for SMTP server authentication when sending emails.
Email:SMTPHost - Name of the email server used by SDx to send emails.
Email::SMTPEnableSSL - The security certificate status of the email server for SMTP server authentication when sending emails. The default for a secured SSL email server is True. A non-secured email server must be set to False.
If you provide an Email::User Name value then Server Manager honors those credentials and sends emails using SMTP authentication.
You can also add the settings in the SDxAppServer.Config file. For example, <add key="Email::SMTPPort" value="587"/>
When you want to export a configuration, the Emailconnectionstring property in SDxAppServer.Config file is exported in plain text format within the entire site information.
The values can then be imported in the same format during import configuration. For
example, <EmailConnectionString>Email::User Name=BusinessAdmin; Email::Password=Admin123; </EmailConnectionString>
