SMTP sending

Sounds like your mail is getting there - but is being refused. They could be bannning your IP or they are reversing looking up your mail mx record and perhaps it is not registered or if you have registered it recently the server they query for DNS has not got the record yet.

Is the domain / MX record registered?

Can you email me direct ian.hutty (AT) intellifix.com - I still think that perhaps your missing my point, but this is not clear since you are using generics in your replies so I'm not sure - you could be using genrics in your replies for security reasons, but you may not be!
