Hi Joe,

I took a quick look at your script and it looks fine.  It's nicely
readable and looks like it should work.  Good job.

I did find a couple of details that you might want to change.  First,
"-W" isn't needed as that's bogofilter's default mode.  Second, since
bogofilter doesn't presently care whether its running with combined or
separate wordlists, those checks aren't necessary.  Of course the
separate wordlist code is scheduled to be deprecated in 0.16.0 and
removed in 0.17.0 so using a single, combined wordlist is the right
thing to do.  Lastly, the "exit 0" statements are unnecessary as they're
in places where nothing more happens in the script.  If they're deleted,
the code will just fall through to the end of the script and exit
normally.
