 * I was going through the wizard and it only offers 3 APIs to use the plugin with.
   In SMTP Postman plugin times, I was able to use out own email relay.
    What would
   cause this limited scope of email relay servers?
 * Thanks

 * Lost you.
 * SMTP support is the same.
 * API is additinal feature that allow you to send more reliable on some hosts –
   blocking smtp ports, etc…

 * He is right I am having the same issue the plugin is forcing me to use the API
   feature only, I used to be able to use the other options before.
 * Now it only shows:
    1- Mandrill API 2- SendGrid API 3- Mailgun API
 * Thanks

 * Ohhh,
    that can happen if your smtp server is not avaliable.
 * Do a “Connectivity Test” to verify that.
