 * Hi [@jiangning](https://wordpress.org/support/users/jiangning/),
 * If you have not already solved this, let me try and help.
 * Your SMTP server (webmail.rozel.com.my) resolves to a different IP than your 
   main cPanel hosting. This is not a problem, but I wanted to check you are not
   trying to send from an email account you created on cPanel?
 * If you’re not sure what that means, please try chamois.mschosting.com as your
   SMTP server and see if that resolves the problem.
 * The other problem is your SMTP seems to be unauthenticated. Please go into ‘All
   Settings’ in PostSMTP and then under the heading ‘Transport Settings’, make sure
   that ‘Authentication’ is set to ‘Login’ and **not** ‘None’, as your SMTP server
   probably requires authentication.
 * Look forward to hearing from you.
 * Kind Regards,
    Tim
