Try the following settings to improve performance:
# Disable all bayes!
use_bayes 0
# Turn off AWL!
score AWL 0
The Auto-Whitelist especially does not like a lot of messages being
passed through it and made a massive different on our own platform
(although we only scan about 200,000 messages/day/machine - but with no
load like you are seeing).
Other things you can try.
- Install RBLDNSD, which creates local mirrors of blacklists you are
using
- Install a local caching DNS server so that the machine does not have
to go off onto the Internet to check things for every mail.
