 * Hi, I believe Gmail is blocking all SMTP connections from your server. Do you
   see any security warning when you login to your Gmail account?

 * Hi there,
 * thank you for your answer but no, Gmail or server are not the issue.
    I installed
   Postman plugin and it works with the same Gmail settings.
