you can use !192.168.1.100 as a NOT statement to remove the machine
from mynetworks. This would still allow that machine to send local
mail, but not relay to outside. Note that exceptions must be listed first.
mynetworks = !192.168.1.100 ... other entries...

If you need to block all mail from that machine, use a blacklist.
smtpd_client_restrictions =
   check_client_access cidr:client_blacklist

# client_blacklist
192.168.1.100 REJECT
