Unhappy Cannot receive emails : DSN: User Unknown

Hi, I'm running an Ubuntu Dapper Drake server with ispconfig installed.

I have been trying to overcome this problem for quite a while and I feel that I'm nearly there.
I have setup email accounts on my server through ISPCONFIG and I can log into them with Outlook Express. However whenever I try to send an email to the account I get bounced back with unknown user
here is the mail log sent with www-data:

Code:
Sep  5 21:33:02 mailserver sm-mta[32024]: k85BX1Nr032023: to=<www-data@mailserver.mydomain.com>, delay=00:00:01, xdelay=00:00:00, mailer=local, pri=32639, dsn=2.0.0, stat=Sent
Sep  5 21:35:26 mailserver sendmail[32130]: k85BZQ74032130: from=www-data, size=260, class=0, nrcpts=1, msgid=<200609051135.k85BZQ74032130@mailserver.mydomain.com>, relay=www-data@localhost
Sep  5 21:35:26 mailserver sm-mta[32131]: k85BZQHP032131: <sales@mydomain.com>... User unknown
Sep  5 21:35:26 mailserver sendmail[32130]: k85BZQ74032130: to="Test - Sales@aaapaints User" <sales@mydomain.com>, ctladdr=www-data (33/33), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=30260, relay=[127.0.0.1] [127.0.0.1], dsn=5.1.1, stat=User unknown
Sep  5 21:35:26 mailserver sm-mta[32131]: k85BZQHP032131: from=<www-data@mailserver.mydomain.com>, size=260, class=0, nrcpts=0, proto=ESMTP, daemon=MSP-v4, relay=localhost [127.0.0.1]
Sep  5 21:35:26 mailserver sendmail[32130]: k85BZQ74032130: k85BZQ75032130: DSN: User unknown
This is the Postfix Main.cf in full

smtpd_sasl_path = /etc/postfix/sasl:/usr/lib/sasl2
smtpd_sasl_security_options = noanonymous
smtpd_sasl_local_domain =

content_filter = amavis:[127.0.0.1]:10024
#receieve_override_options = no_address_mappings

virtual_maps = hash:/etc/postfix/virtusertable

mydestination =

masquerade_domains = aaa-paints.mydomain.com !aaa-paints.mydomain.com
masquerade_exceptions = root

# Requirements for the HELO statement
smtpd_helo_restrictions = permit_mynetworks, warn_if_reject reject_non_fqdn_hostname, reject_invalid_hostname, permit

# require proper helo at connections

# waste spammers time before rejecting them
smtpd_delay_reject = yes
disable_vrfy_command = yes
I'm sure there's something wrong in here.

Here is the ouput of "ls -la /root/ispconfig"

I do have a codomain for my website with an empty host, which often is the problem for a lot of people. Also my virtusertable and local-host-names files are configured correctly
Maildir is enabled in ISPCONFIG

I just can't seem to pin point where this is going wrong. The only problem is the incoming emails. I can log into the user accounts and send emails fine with outlook.
Thanks heaps for any help you have.
