If one SMTP client make a SMTP connection to backend server,the backend server doesn't know 
whether it is from outside world or from my user's outlook until this "SMTP client" send "AUTH LOGIN"
command to backend server,but at this initial connection moment,backend server has to "make a decision" that whether accept this SMTP connection or drop it.
So I cannot "Differ them by authentificated-status, not by IP range."

This is just a "case"  :)
I want to make an anti-spam solution for "any" backend mail server,
no matter what MTA and database the backend server use.
And also the backend mail server config and other stuffs 
(such as MX record ,IP of backend server,POP3 and SMTP server setting in the user's outlook )
don't need to be modified   

It is that "backend server serve for both inbound and outbound mails " 
results in the difficulty in this case. 
If backend server just serves for inbound mails (another server serves for outbound mails ) ,
the solution will be made much more easily
