<para>The <filename>/etc/aliases</filename> file that was just created,
the <filename>main.cf</filename> and the <filename>master.cf</filename>
must be personalized for your system. The <filename>aliases</filename> file needs your 
non-root login identity so mail addressed to root can be forwarded to 
you at the user level.  The <filename>main.cf</filename> file needs your fully qualified 
hostname.  The <filename>master.cf</filename> needs to be modified to prevent your machine from 
becoming a relay for unauthorized entities.  All of these edits can be done 
with sed commands entered into the console with appropriate substitutions of 
your non-root login name for [user] and your fully qualified hostname for 
[localhost.localdomain]. You will find the <filename>main.cf</filename> file is self documenting, so load it into your editor to make the changes you need for your situation.</para>

<para>To automate the running of postfix, use following command to create the init.d script:</para>

#!/bin/sh
# Begin $rc_base/init.d/postfix
