#myhostname, I should uncomment and put my hostname, i.e. the name I gave my VPS, right?
Or does it just go
myhostname = mydomain.net, in other words don't edit the phrase 'myhostname' except to uncomment?
#myhostname = virtual.domian.tld is that to put a subdomain?
Should I add a listing for all including with and without
