Mail issues with "The Perfect Server - CentOS 5.2 x86_64"

[dp6ai]

--------Please ignore this-------------
I should have checked my host didnt have port 25 blocked

---------------DOH-------------------

I'm hoping someone can help.

I've followed the above tutorial also installed ISPConfig and all is working well. I'm able to create new sites etc with no issues.

The one problem i'm having is with sending and recieveing mail . I've spent hours going round and round in circles but with no success.

Via roundcube
if i try to send a mail to a gmail account:
i have the following issues
1) The roundcube "Sender address" is "web_user <user@www.domain.co.uk>
2) The mail never arrives and i get the following in /var/log/maillog
