This would require running the same Berkeley DB version (with same
compilation options) on both your server and your laptop computers
underneath bogofilter.

You can put "db-log-autoremove  = Yes" in the configuration file to
have the log files removed automatically. Other than that, this is the
right way to portably copy data around.

NOTE! bogoutil -l merges the text file into the existing database,
adding counts for tokens that are already present, so you'll probably
need to "rm wordlist.db" on the mail host before using bogoutil -l,
otherwise, you'll register older tokens over and over. This, of course,
is not an option if you have several other training sources.
