sa-exim cvs with greylisting support

I've implemented greylisting support in sa-exim mostly via a patch to
SpamAssassin.
This implementation is actually better than regular greylisting as it only
happens for messages that SA scores in the middle (i.e. not certain it's ham
or spam)

You can find everything here:
http://marc.merlins.org/linux/exim/files/sa-exim-3.1+cvs.tar.gz

the docs and explanations are here:
http://marc.merlins.org/linux/exim/files/sa-exim-cvs/README.greylisting

My spamassassin patch is here:

I'd love feedback before I release this as sa-exim 3.2
This is the changelog BTW:

Let me know what you think or problems you find

Thanks
Marc
