Are you using Postfix and is your server on the Internet (not behind
another server)? Do you reject mail to unknown users? Do you
have any other anti-spam measures in place in front of amavisd-new? I
find policyd-weight (set to a permissive 4.2) very safe and
quite valuable. My primary server rejects 85% of the mail before
amavisd-new sees it and this is done without configuring RBLs or
using greylisting in Postfix. On my secondary server I can afford to
be more aggressive therefore I use greylisting and a couple RBLs
and I get a 99% rejection rate on that machine. I made a HOWTO for
Debian users (but much of it would apply to any Postfix box).
