Simply specify one single exception for them

Her you add:
    check_client_access hash:/etc/postfix/ignorants

and in /etc/postfix/ignorants you list:
the.ignorant.sip.address OK

If you bought $1000 worth of Nortel stock one year ago, it would now
be worth $72. 
If you bought $1000 worth of Budweiser (the beer, not the stock) one
year ago, drank all the beer, and traded in the cans for the nickel
deposit, you would have $79. 
My advice is to start drinking heavily.
