I have installed iRedmail successfully using the above tutorial. The SSL that InstantSSL provides is a 90 days free trial. After that we have to pay. So I avoided "Step 4 - Add SSL Certificate" in the above tutorial.
Now I have 2 weird problems:
1. I am not able to use www with my domain name in the browser or in the ping.
www.mydomain.org/iredadmin shows "Server not found". Ping works only without www.
2. I am not able to use http, but https works.
https://mydomain.org/iredadmin works fine, but http://mydomain.org/iredadmin shows "Not Found" page.
Could you please help me to understand what went wrong ?
