I'm trying to set up a mail server using this
But i'm a bit confused about the /etc/hosts. Here's what's confusing me:
(1) (2) (3)
192.168.0.100 server1.example.com server1
(1) The first thing is my LAN IP address which is 10.0.0.2 on my server.
(2) The next thing is confusing. Let's say i'm hosting this domain on my Ubuntu box www.123.com
and my mailaddress should look something firstname.lastname@example.org
What should the "server1.example.com" look like in my case?
(3) This make a bit sense to me (alias, wright?)
Thanks - hope not that this is a too stupid question
