Have you used and not something as as hostname when you installed the server? Then you should change the hostname to in /etc/hosts, /etc/mailname, /etc/postfix/ and /etc/hostname or email will not work.

Then create a dns A-Record for and that point to the IP address of your server. If the system shall be reachble from outside of the internal network, then you have to use the external IP address of your router for the dns records and then forward port 8080 and all other ports that shall be accessible from outside from your router to your server.
