[Clark, Aaron]

Hi All, 
 
I'm a newbie with Linux and Bogofilter. I'm currently trying to implement a
Mail Gateway to front my Exchange server for content filtering. I've loaded
RedHat 8.0 with Postfix to receive mail and relay it to my internal Exchange
server. I have now implemented the script in integrating-with-postfix and
have performed very little training, SPAM - 150, GOOD - 30. Now when mail is
passed to my Exchange server the email is blank including the subject line
and body. 
 
To help remedy this problem I've updated Bogofilter to 0.13.7 and tried to
make minor changes to the filter script. I don't seen anything out of the
ordinary in the maillog. I'll add the contents of my filtermail.sh at the
bottom of the email.
 
Should I even be doing it this way or should I use procmail?
 
Any help would be appreciated, 
Thanks,
Aaron

# Clean up when done or when aborting.
trap "rm -f inp.$$ msg.$$; exit $EX_TEMPFAIL" 0 1 2 3 15
 
# bogofilter returns: 0 for spam; 1 for non-spam; 2 for I/O or other errors.
rm -f inp.$$ || exit $EX_TEMPFAIL
cat > inp.$$ || exit $EX_TEMPFAIL
$FILTER -f -u -e < inp.$$ > msg.$$ || exit $EX_TEMPFAIL
 
exec $POSTFIX "$@" < msg.$$
exit $EX_TEMPFAIL
