I do the exact same thing but call it MY_EVIL :) 

I didn't know how many I could place in either. So I put about 15-20 then
make a MY_EVIL2, and so on.  I sift thru the spams every once and a while
for the evil domains. I will start to manually expire a few so spliting them
up will help. As the lower numbers will be the oldest domains. 

These aren't the domain of the sender, but the URL of host. (IE:margate.com)

So short answer is : I don't know. :P
