It is unclear for me what you want to achieve.
Do you want me to run this mailserver locally?
Or help you to configure it on your host?
If former it is easy, I almost done this.
If later then what problems do you have. Instructions you reference to is very clear for me.
Hello Sir,
Installation would not take enough time however testing may require more time, that is the reason I kept it for 3 days.
Kindly ping me so that we can discuss more on this.
With Regards
