Here is how to do it with stunnel.
First download the stunnel install file. If the following link is out of date or broken search the internet for a new stunnel download link.
Install stunnel. Note: During the the installation a black cmd screen opened requesting location information. I did not type in any information and merely pressed the Enter Key at every request untill the cmd screen closed. Note: On this current test I filled in UK and the remainder blank.
After installation a stunnel icon should be on the desktop. Click on the trunnel icon and open the stunnel configuration file. It should open in NotePad. Edit the stunnel.conf file in accordance with the above referenced Forum instructions. A copy of my edited file (stunnel.conf), current at Dec 2013, can be found in Stunnel Config.zip., See - Download.
Click the Test.
Open up MT4 Terminal (Ctrl + T) and select the Journal Tab and check under Messages if the the Test was successful.
