The spamassassin service has all of the options hard-coded in the
initscript, which is less than ideal for actually being able to change
them. An (optional) /etc/sysconfig/spamassassin as is done for a
number of other services would make this easier to tweak.
# Set default spamd configuration.
SPAMDOPTIONS="-d -c -m5 -H"
# Source spamd configuration.
if [ -f /etc/sysconfig/spamassassin ] ; then
It already does so.
Sorry, blindness or lack of sleep one (or both :)
