That will disable postgrey, but isn't enough to enable postscreen. There are a couple of daemons you have to enable in master.cf (steps 2 through 6): http://www.postfix.org/POSTSCREEN_README.html#enable That README refers to lines that are commented-out in master.cf; of course, if you've upgraded from an earlier of postfix, you won't have them. What I did was to untar the latest postfix release under my home directory, and find the master.cf that ships with it. Then, I copy/pasted the lines mentioned in the README over to my real master.cf. After a restart, you should see lines like this in your mail log: Dec 6 03:13:46 mx1 postfix/postscreen[2810]: CONNECT from ... that let you know its' working.
