Best update that is missing from the Postfix book is the ease of
configuring Amavisd-new to use a temporary file system.
Add to your /etc/rc.conf the line: amavisd_ram="100M"
This is much simpler than the steps on Patrick's site and in the Postfix
book. On my lowly 333mhz system, typical Amavisd processing dropped
from 40s to about 4s, and allows me to run Amavisd as a pre-queue filter.
I picked 100M as a starting point on my 512M system, and still have
plenty of free memory with my current config. (top shows 168M Inact)
