I don't understand. I thought the question in exim configuration 
referred to my own set up. I tell exim to use smart host for my 
outcgoing mail. The address mail.guardedhost.com is simply the mail 
serrver address to which I send outgoing mail.

My understanding is that the mail server to which I send mail 
understands SMTP.
