 * Other interesting facts:
   1. We host the the web server on a Windows server2. 
   The SMTP is an external one3. We created a test .Net console app and deployed
   it to the same web server. It sends emails with no problems using the same parameters
 * To conclude:
   – PowerShell script and a Console .Net app work fine and can send
   emails– None of the plugins, nor the native WordPress emailing can not send mails(
   authentication failed)Not sure if it matters but we also use wordfence as a part
   of the web site.

 * Hi Dake,
 * I tried using Easy WP SMTP and the same problem occurred.
 * However, if I exclude authentication from settings on the WP Mail SMTP page, 
   than it works.
 * A question:
   The access to the SMTP server is limited so it ONLY accepts traffic
   from the web server address _62.162.94.138_ on port 5588. That is why the PowerShell
   script works fine when executed directly on the web server machine.. Is it possible
   that the plugin when installed under WordPress may use a different IP address
   or port?
