Matthias,

What would happen if your system had a special group for running
bogofilter, e.g. bogo, and used SGID for the bogofilter directory and
bogofilter and bogoutil executables?

As a quick test, the following seems to work:

   mkdir bogodir
   chgrp bogo bogodir bogofilter bogoutil
   chmod g+s  bogodir bogofilter bogoutil
   ./bogofilter -d bogodir --db-transaction=yes -n < /dev/null
   ls -l bogodir
