Just finished installing sendmail and was able to successfully send an email from the command line. However, the sender address was from root@EquinoX. I want to be able to change this so that the sender is from firstname.lastname@example.org. How do I do this?
I have changed my /etc/mail/local-host-names so that the only entry it has now is mydomain.com I have setup a A record, so that mydomain.com points to the server
When I restart sendmail I got
hostname: Name or service not known, why is this?
