Configuring DNS and postfix on Ubuntu

Sample configuration of bind9 dns server and postfix mailserver on Ubuntu:

Test script:
#!/bin/bash
# Testscript smtp mailserver
# Please pipe output to telnet

port=25
time=1

echo open $host $port
sleep $time
sleep $time
echo mail from:$from
sleep $time
echo rcpt to:$to
sleep $time
echo data
sleep $time
echo subject: test on `date`
echo Hello, test on `date`
echo .
echo quit

Voor mensen die niet kunnen telnetten naar hun ip, maar wel naar hun localhost:
"vi /etc/postfix/master.cf"
smtp inet n - n - - smtpd
Dit lijntje aanpassen, zie dat de 2e "n" er staat!

This is about setting up DNS on the server, not the dns record so that postfix can get mail.
