Question getnameinfo failed Postfix Virt domains - falko

Hi all.
I have installed postfix using virtual domains on a fresh ubuntu install using falko great howto: Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 8.04 LTS)
All tests appear to reply with correct responses as per the howto. I can get into database using phpmyadmin. I have setup two user accounts this way, 'news@scribalpublishingmail.com.au' and 'test@scribalpublishingmail.com.au'.
using mailx I have sent each a welcome email.
I have registered the domain name and arranged DNS hosting. they say they can see the mail server. I have forwarded the required ports on my router.
I have sent an email to news@scribalpublishingmail.com.au from two seperate external email accounts and neither of them have bounced.

I can browse to suirrelmail across my network using the ipaddress/squirrelmail/ but it will not let me sign in to either of the accounts that I setup.

Then I noticed that the result of
netstat -tap
root@smail:/home/alan# netstat -tap
Active Internet connections (servers and established)

getnameinfo failed

on the second last line it says: getnameinfo failed

here is my postfix info

vi /etc/postfix/main.cf
# See /usr/share/postfix/main.cf.dist for a commented, more complete version

# Debian specific: Specifying a file name will cause the first
# line of that file to be used as the name. The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname

smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no

# appending .domain is the MUA's job.
append_dot_mydomain = no

# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h

readme_directory = /usr/share/doc/postfix

# TLS parameters

smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache

# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.

myhostname = smail.scribalpublishingmail.com.au
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = smail.scribalpublishingmail.com.au
mydestination = smail.scribalpublishingmail.com.au, localhost, localhost.localdomain

virtual_mailbox_limit_override = yes
virtual_maildir_limit_message = "The user you are trying to reach is over quota."
virtual_overquota_bounce = yes
I noticed in another thread that falko advised someone to change

myorigin = /etc/mailname
myorigin = their fqdn

as I have done above but it has not changed anything
and below:
root@smail:/home/alan# netstat -tap | grep mysql
tcp 0 0 localhost.localdo:mysql *:* LISTEN 4445/mysqld
getnameinfo failed
result of telnet localhost 25
Connected to localhost.localdomain.
Escape character is '^]'.
220 smail.scribalpublishingmail.com.au ESMTP Postfix (Ubuntu)
does anyone have anyideas where I should look. Im sure there are no typos as I copy and pasted everything in (being very careful about extra spaces as many have warned.)

Any help would be greatly appreciated.
