I have a particular server running spamd which uses bayes every time I
test it by hand, but apparently never when it goes through exim/spamd.
I run everything (both the spamd daemon and the manual tests) as user
spamd. I checked the permissions on the bayes database. I use a global
bayes database in /var/spool/spamd/bayes/. I ran "spamassassin -D
--lint" - and I get no failures - both as root and as the user spamd.
In spite of all of the above, it looks pretty clear that bayes is only
used when I run an email manually through spamassassin, but not when it
goes from exim through spamd.
Here is the report when ran from the command line:

Bayes is clearly not being used when it goes through spamd. Does anybody
know what could be causing this?
