I built a stand alone server using Ubuntu as the OS. I have installed mailcow and believe its working. I cannot test it as it will clash ( I think) with my existing email server. I am ready to test/switch it over and before doing that I wanted to check/ask the following: 1. How do I check what host name and IP mailcow is configured for? 2. if I change the server's IP, would I need to change anything else. I will be connecting it directly to internet using my public IP address. I have configured the DNS both in mailcow and Godaddy. My current server is behinf the firewall and is NATted. Thank you. Darryl.

Can I change the IP address of the system without causing mailcow to fail?

if I change the server’s IP, would I need to change anything else. I will be connecting it directly to internet using my public IP address. I have configured the DNS both in mailcow and Godaddy. My current server is behinf the firewall and is NATted.

mailcow uses the IP address of the host its running on.
The “hostname” e.g. mail.domain.com is configured during initial setup of mailcow, and that is not necessarily the name of the host its running on.
I think it is a good idea you review the documentation chapter of DNS and double check everything.
