Hello, https://www.digitalocean.com/community/articles/how-to-install-iredmail-on-ubuntu-12-10-x64 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 ? THanks.
