a dot alone in a line (bug?)

[Dominique VOLPE]

Hi,

I tried to classify directly a test message in a command line and the 
bug I reported didn't occur.
It is very strange because in the logs of Postfix, I can undoubtedly see 
that the messages containing a single dot are shortened after they 
passed thru Bogofilter.

In master.cf, I have :
------------------------
xxx.xx.x.xx:smtp      inet  n       -       n       -       -       smtpd
        -o content_filter=filter
filter    unix  -       n       n       -       -       pipe
  flags=R user=filter argv=/home/filter/scripts/postfix-filter.sh -f 
${sender} -- ${recipient}
------------------------



And here is the script "postfix-filter.sh" :
------------------------
#!/bin/bash

FILTER=/usr/local/bogofilter/bin/bogofilter
FILTER_DIR=/home/filter/spool
POSTFIX=/usr/sbin/sendmail
export BOGOFILTER_DIR=/home/filter/data

# Exit codes from <sysexits.h>
EX_TEMPFAIL=75
EX_UNAVAILABLE=69

cd $FILTER_DIR || \
    { echo $FILTER_DIR does not exist; exit $EX_TEMPFAIL; }

# Clean up when done or when aborting.
trap "rm -f msg.$$ ; exit $EX_TEMPFAIL" 0 1 2 3 15

# bogofilter -e returns: 0 for OK, nonzero for error
rm -f msg.$$ || exit $EX_TEMPFAIL
$FILTER -l -p -e > msg.$$ || exit $EX_TEMPFAIL

exec <msg.$$ || exit $EX_TEMPFAIL
rm -f msg.$$ # safe, we hold the file descriptor
exec $POSTFIX "$@"
exit $EX_TEMPFAIL
------------------------


I'll do more tests next week.
