Question : Exchange 2007 SBS - Cannot send external e-mail.

Hi,

I'm having difficulty trying to get Exchange to send external e-mails on my SBS 2008 server.
Internal e-mail works great and I can also receive external e-mail. I have a send connector
set up and have added the address space which points to *. I'm using DNS MX Records to route the mail.

Thankyou.
