Thanks for a great server software!
I am running it on my Debian 8 with great success - except for the mail part.
I have installed the Webmin and Virtualmin, and set the DNS for some domains like frios.dk and fricomputer.dk - and the website works great.
But somehow I can’t get the Mail Server up and running, so I can get my very own mail server.
I have tried everything, check the ports in the router is open, I have run a https://www.digwebinterface.com/ to see if the MX records is active, and they are. I can ping the server from the outside and so on.
What have I missed?
