Some caveats for this advice: it is true only if your user for the
MIMEDefang processes (in my config, defang) has rw access to the default
directory that SpamAssassin uses for the bayes_* files, which is
/root/.spamassassin/ IIRC.  If you create a limited rights user you
don't give it access to root's subdirectories so the Bayes stuff will just
silently not do anything.  Manually setting the config option to a
location to which the MIMEDefang user has rw access will allow it to
function.

It would be nice if SA noticed this and reported the error.  We are all
NOT running MD and SA as root, right?  :)

200 each is the default.
