+In this example we can see that the hostname is the default value of <color #ed1c24>localhost.localdomain</color> and we want to change this to something that we can use and recognise.
+\\
+\\
+To set the hostname use the following:
+    hostnamectl set-hostname 'your-hostname'
+\\
+\\
+For example, lets say I want to change the hostname to be mailsvr, then I would use:
+    hostnamectl set-hostname mailsvr
+\\
+\\
+We can now check the hostname from the console again using:
+    hostname
+    or
+    hostnamectl
+\\
+\\
+The hostname returned will now be the one you set (mailsvr) in this example.
+\\
+\\
+We also need to edit the following file:
+    /etc/hosts
+\\
+\\
+Add a line at the end of the file with your <color #ed1c24>Alma Linux IP</color> and the <color #ed1c24>hostname</color> you just used:
+<file>
+.0.0.1   controller localhost.localdomain localhost4 localhost4.localdomain4
+::1         controller localhost.localdomain localhost6 localhost6.localdomain6
+.10.10.1    mailsvr
+</file>
