I did hat you were telling, and it works now. Thank you very much

OTHER QUESTION??

I'm using this server to communicate with smtp.auth.orange-business.com,  
as you already understood and solved.
How can I use this server as a secure relay server for sending email to  
orange?
I mean, use credentials, or restricting domains, connecting from the  
outside world.

I wouldn't know where to put the credentials now.
