After much trial and error tonight, I have found the following entries in
my spam.assassin.prefs.conf file provide the fastest scanning performance:
# don't mess with mime encoded messages
# don't do dns based rbl lookups
# only check for a valid MX record once
Turning on rbl checks can be expensive, but usually don't hurt too much (I
recommend running a local caching bind server on the same box that
MailScanner is on).
The big "slowdown" is the check_mx_attemps, by default it is set to 3
attempts with 5 seconds in between (!), which can mean extra long delays if
the domain being checked has a DNS server problem or doesn't have a valid
Hope the above helps someone.
