Install as per normal

apt-get install postfix
Choose Internet Site Config.

After Install - Main folder = /etc/postfix
Main file = main.cf

Basic Changes:

Just the name used to identify server
myhostname = mail.domain.com
//disable lookup of usernames disable_vrfy_command = yes Remove hash beside delay_warning_time = 4h

Advanced Changes:

To prevent cross over emails between multiple domains - e.g. where root@mydomain1.net and root@mydomain2.net are on the same server.
smtpd_sender_restrictions = check_recipient_access hash:/etc/postfix/restrict

To activate/ add this file into postfix ->
postmap /etc/postfix/restrict


SENDING AN EMAIL VIA TELNET 25 & Testing forwarding

mail from: sri@mara.net
rcpt to: user@lastre.com
data
.
quit

Test and get working Normal - Should be able to send and revieve via pine etc.

Had to adjust /etc/hosts with domain name (this allowed sending emails ok):

127.0.0.1       localhost
136.201.1.250   kartbuilding.net        phidebian
