email sebd receive problems

[patfee]

Hi,
For some reason i cant send and receive emails.

I have followed the perfect centos 5 setup
ISPconfig mail setup is
Postfix
/etc/postfix/virtusertable
/etc/postfix/local-host-names
/var/log/maillog

I can connect through pop3 with outlook on the pop3 server locally, and when i try to send an email through this account i receive the following error>

The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'x.x@gmail.com'. Subject 'test', Account: '192.168.1.67', Server: '192.168.1.67', Protocol: SMTP, Server Response: '554 5.7.1 <x.x@gmail.com>: Relay access denied', Port: 25, Secure(SSL): No, Server Error: 554, Error Number: 0x800CCC79

And the x.x@gmail.com definitely exists

trying to send an email, from my gmail acount, i receive the following error
This is an automatically generated Delivery Status Notification

Delivery to the following recipient failed permanently:

x@x.com

Technical details of permanent failure:
PERM_FAILURE: SMTP Error (state 13): 550 5.2.0 <x@x.com> No such mailbox

whereas i can definitely login through my servers webmail using this x@x.com account.

any sugestions please?

thanks
Patrick
