I was also using Exim 3.x and looked into it myself. Turns out it seems much 
easier to do in Exim 4.x. The local_scan feature described in chapter 38 of 
the exim documentation that I used to implement greylisting doesn't exist in 
Exim version 3.x.

Why don't you upgrade to a newer version of Exim?

I'd be happy to share my greylisting code if you want to use Exim 4.x. Just 
download the source code for Exim 4.20 from www.exim.org, add my greylisting 
code and you can be in business.
