Running own mail server

[Dan McCullough]

You need to setup "name servers" you can do that on your box, and then
in your domain account you can set the name servers as
ns.yourdomain.com, typically you need two IP addresses for two name
servers, however if you do not want to do that you can get a secondary
name server from one of the free dns hosting services, like
http://www.xname.org/ and there are others you can google them but the
names excape me.

THIS SHOULD NOT BE TAKEN AS GOSPEL, and there are others on here MUCH
MUCH better at this then I am, but this should get you started.  You
will need BIND/DNS server installed on the box.

the dots after the domain name is not a mistake.
