Postfix (main.cf) is now set up with the changes above. If you need to make
changes, edit /etc/postfix/main.cf (and others) as needed. To view Postfix
configuration values, see postconf(1).

After modifying main.cf, be sure to run 'systemctl reload postfix'.

Do you have a cartridge return on the end of your hostname. I suspect this is missing and throwing out the update. If you open /etc/hosts with a text editor, then scroll to the end of the last line and press ENTER then save the new file it may help

"bad parameter value: tomcp-Precision-5520.."

There seems to be an extra dot after the hostname

What is the output of

uname -a
hostname
cat /etc/hosts

Can you help with this problem?
