If I clear "Anonymous Access" option on SMTP Virtual Server 
>Properties>Access>Authentication, the authenticated users cannot send any
mail over Exchange 2003 server. I think that is the secure way to disable
this option because of relay, or not?
They have the following error if they send any mail through Exchange 2003:
"454 5.7.3 Client does not have permission to submit mail to this server."
