Hi Chris,

Sorry to hear you're encountering difficulties.  Let's see if we can
figure what's going on...

A "mv" failure sounds like permission problems with the parent
directory.  What does 

  ls -la /home/vmail/maildirs/cwilkes/.bogofilter/.old

report?

Not by itself.  A Berkeley DB environment includes _all_ the files in
the directory.  As long as _NO_ bogofilter process is running, you can
cheat and use "cp -f bf_compact.$$/* $BOGOFILTER_DIR".

That's an odd one.  Bogofilter's DEBUG macros (activated by "-x ...")
should help us.  What's the output of command:

   echo this is a test | bogofilter -x d -vv -C
