Hello Thomas,

Sorry, but I don't recall previous reports of bf_compact nuking the
wordlist as happened to you.  Can the problem be reproduced or is it a
one time occurrence?

If the problem is repeatable, you can run bf_compact and trace its
execution by adding " -x" at the end of its first line.

8192 is the size of a new (empty) database.  One can demonstrate that
via "bogoutil -l new.db < /dev/null && ls -l new.db", 

bf_compact saves the original directory, i.e. ~/.bogofilter as
directory.old, i.e. ~/.bogofilter.old.  Have you looked to see if you
still have that directory?

HTH,

David
