I've got my site all up and running but it doesn;t seem to be firing any emails during the order process. Any idea how to debug it.

I've got a mailbox set up on the domain and made sure it authenticates to the outgoing smtp server but still nothing seems to be happening. Any ideas..

Make sure you've updated the web.config file and the mail settings section.

     <system.net>
         <mailSettings>
             <smtp from="your@emailaddress.com">
                 <network host="mail.yourmailserver.com" password="12345678" port="25"  userName="sample"/>
             </smtp>
         </mailSettings>
     </system.net>
