Greylist in DB

Hi, me again, 

i have read a thread in october about the greylisting information are
not nessessary on the mail server but on the SA server. So what if i
habe x SA servers? I certainly could share the information via nfs, but
that is slow. i have read and seen the case statement in Greylisting.pm
where i can enter the DB code. But does anyone know if the code is
already written (i cant write perl) and where to download it?

regards Martin
