Or another possibility is that the config points to a specific bayes
database but the permissions are set so that only root can read it. When
Mailscanner runs spamassassin as postfix it cannot read the database.
Personally I use a mysql database as the backend for the bayes database.
I run mailwatch aswell so need a database for it and moving bayes over
to use a database is very little extra work and had the benefit that it
makes it easier to add additional mailscanner boxes in the future.
