Domain and IP address setup

to run apache and postfix

[satimis]

Hi folks,

Ubuntu-6.06.1-LAMP-server-amd64
Apache2
Postfix

For testing Apache and Postfix I have a free dynamic domain setup on dyndns.org with a free hostname and dynamic IP asigned.

Please advise which file/files I have to edit so that I can;

1)
send email
2)
people can browse my website to be created later.

TIA

I'm running ADSL broadband with dynamic IP.

B.R.
