Exchange Connector SMTP Not Working

Hi Gang,

I have a strange problem with Exchange 2003, Domino Connector and Domino 7.0.3. We have recenly joined with a company running Exchange 2003. We have setup a Exchange Connector between both Company. I was asked to set it up to only send mail via SMTP and not via the internal route. It works for most of the users correcly. Some Users however, when they send SMTP Mail it gets sent to the Exchange.box and gets stuck there. It gets address in the format of name@smtp.com.au@domain

If I remove the @domain part it gets sent via the normal SMTP task in Domino. How do I force these messages to be sent via SMTP

Regards,

Michael
