[plug] Need some postfix help

[Jon L. Miller]

I'm in need of a postfix guru, someone that understands all the various
commands.  I need to tighten down a postfix system.  The area I'm having
issues is within the following lines. What has happened is the mail
bounces back to the sender.  For the meantime I have them using the
configuration that I created some time ago and mail is flowing.  The issue
is there are ways to tell postfix to only allow certain mail destined to a
particular domain and user in.  Since these are the latest commands I've
added I decided to rim them out until I can find the culprit.
The error messages are:
NOQUEUE: reject: RCPT from unknown[203.153.242.19]: 554 5.1.2
<user at abc.com.au>: Recipient address rejected: Domain not found;
from=<jlmiller at mmtnetworks.com.au> to=<user at abc.com.au>    proto=ESMTP
helo=<mail.mmtnetworks.com.au>

warning: regexp map /etc/postfix/helo.regexp, line 1: using empty
replacement string
warning: regexp map /etc/postfix/helo.regexp, line 2: ignoring
unrecognized request

restriction `reject_non_fqdn_hostname' after `permit' is ignored
warning: /etc/postfix/header_checks: logical line must not start with
whitespace: " if /^Received:/     /^Receive..."

warning: restriction `reject_non_fqdn_hostname' after `permit' is ignored


I'll be going through some of the files in /etc/postfix to view the above
complaints.
