I think I found the problem. It must have updated
/root/.spamassassin/user_prefs to 8.0. and since I'm using root to run
spamd...
Although I did have it running as spamd and it was still using 8.0 and
spamd does not have a user_prefs, so I'd assume it would use the
local.cf file at that point
recently did portupgrade for spamass-milter, now running
spamass-milter-0.3.1_3. The new required scores are being set at 8.0
instead of the default 5.0. Nothing in UPDATING about any config changes.
Here are my spam processes, running like before, no changes to rc.conf
ps -auwx | grep spam
no
