+         Donot change mailer-app-args.
+         You will also need to download a sendmail clone for Windows (msmtp). This version works without issue:
+         http://msmtp.sourceforge.net/index.html. Download and copy the .exe to %winddir%\system32.
+         You'll need to create a small config file for smtp credentials (host name, authentication, tls, etc.) in
+         %USERPROFILE%\Application Data\ called "msmtprc.txt". Below is a sample copy of this file:
