Milter-greylist

Hi,

I've tried to upgrade our mail servers (sparc running Solaris 2.8) from 
1.5.3 to 1.6rc1. I've noticed almost immediatly that the memory usage 
climbed from ca 15MB to more than 220MB for a greylist.db that is around 
100k entries. This makes the new version almost unusable on our current 
machines (Netra X1 with 512MB of RAM).

Any ideas of what could cause a so big difference ?
