Jerry,

I see several problems in the snippet above.  First, the "-f" flag is no
longer accepted by bogofilter and causes it to exit.  (Try running your
bogofilter command "/usr/bin/bogofilter -f -p  -u -l -e -v" from the
command line).  Second, the procmail recipe doesn't include any error
recovery, which makes it possible for a bogofilter error to lose mail.
Lastly, the "* ? bogofilter" line runs bogofilter a second time, which I
think is unnecessary.

My procmail recipe is shown below.  It causes procmail to retry in case
of error (which helps prevent lost mail) and it checks the message for a
bogofilter spam indicator -- proof positive that bogofilter _has_
classified the message.
