Re: [exim] Greylisting - how do you implement?

I have a reall simple way to do it. And I'm using it on several hundred
domains and it works. Suppose you have 1 MX record. Add 2 more dummies.

dummy1.example.com 10
real.example.com 20
dummy2.example.com 30

Gets rid of almost all your bot spam and is far faster and easier than
greylisting.
