I've got a cheap and cheerful dedicated server from 1and1 that I use to send emails. The received email header looks like this:
Received: from s123456.onlinehome-server.info (s123456.onlinehome-server.info. [18.104.22.168])
I'd like that to say
Received: from my.awesome.domain (my.awesome.domain. [22.214.171.124])
Another answer I've read suggested "making a change to the /etc/hosts file, which looks like this:
127.0.0.1 localhost.localdomain localhost 126.96.36.199 s123456.onlinehome-server.info s123456 188.8.131.52 s987654.onlinehome.info
I'd nervy about adding or changing anything in that file and getting it wrong - do I just need to add
on the second line?
