This is documented at
"http://www.zmailer.org/zman/zadm-smtpserver.shtml".  You need to turn
on the "enable-router" option and then set the appropriate "EHLO-style
options" for checking "from" addresses, "to" addresses or both.  The
default "smtpserver.conf" file contains comments which should help you
do this.
