This is similar to what graymilter <URL:http://www.acme.com/> does. 
Graymilter does not work with triplets, only with the sender's IP 
address.  So to be effective you have to have longer graytimes (I use 5 
hours).  Having graytimes like 5 minutes without triplets means that 
spam will get through.

I've written some patches to graymilter to support domain based 
whitelisting for the graymilter which you can find at:


Right now I am using the third of the described versions and it seems to 
be working well enough.
