7 For what it's worth, recent versions of postfix ship with a
8 pre-screening daemon called postscreen. It has a suite of tests that
9 work after the initial greeting, and thus have the "negative" side
10 effect that the client must be disconnected (temporarily) if it passes:
14 The main limitation of "after 220 greeting" tests is that a new
15 client must disconnect after passing these tests (reason: postscreen
16 is not a proxy). Then the client must reconnect from the same IP
17 address before it can deliver mail.
19 In other words, it greylists them. So if you're already running a
20 separate greylisting daemon, it's safe for you to enable postscreen and
21 turn on the "deep protocol tests" (see the README). That way you get
22 postscreen's benefit for free and don't need to worry about running a
23 separate greylisting daemon any more.
