   Postman is properly configured, but another plugin has taken over the mail service.
   Deactivate the other plugin.
 * Please advise..

 * The three causes of this message (that I’m aware of) are :
    - The theme you are using is sending mail – temporarily activate the default
      TwentyFifteen theme to see if the error goes away
    - Your host may have installed an MU-class plugin to prevent you from sending
      mail – check your wp-content/mu-plugins directory for hidden plugins
    - Another plugin is sending mail instead of Postman – temporarily deactivate
      all other plugins to see if the error goes away

 * If you run the Diagnostic Test, there is a line that begins Postman Bind… Followed
   by a long file name. That file name shows the other code that is using wp_mail.
