[ale] First time setting up mail server (postfix & dovecat)

[Jim Kinney]

In order to recieve email, the interwebs must be able to find your system.
That is done by the host and domain name. You will need to be using real
ones so postfix will understand what domains it's really supposed to accept
mail for.

I have the domain jimkinney.us. So I put that into my mailserver so it
knows where it is. I have my DNS records set to send mail to my server (
barkingcat.jimkinney.us). So the mailserver knows it's name is barkingcat
on the domain jimkinney.us. Now when mail is _sent_ it shows in the headers
to have been sent from me at jimkinney.us and it originated from
backingcat.jimkinney.us.

So you will need to put in your FQDN (mine is barkingcat.jimkinney.us) for
the hostname and the full domain name (mine is jimkinney.us).

Every time you stop a school, you will have to build a jail. What you gain
at one end you lose at the other. It's like feeding a dog on his own tail.
It won't fatten the dog.
