[exim] anyone using the greylisting from the wiki?

I'm using ASSP atm, and it's good, but I loose all kinds of exim
functionality and logging such..

I saw the wiki had a little greylisting script w/o a database..
http://exim.org/eximwiki/DbLessGreyListing

It looks good.. just wanted to know if anyone is using it.

Thanks in advance.
