Hi
Auto added footer is very bad but nn one of server i have:
smtp inet n - n - - smtpd -o
content_filter=stopka
stopka unix - n n - - pipe
flags=Rq user=filter argv=/home/filter/add_filter.sh -f ${sender}
-- ${recipient}
#!/bin/sh
INSPECT_DIR=/home/filter/filter
SENDMAIL=/usr/sbin/sendmail
EX_TEMPFAIL=75
EX_UNAVAILABLE=69
# Clean up when done or when aborting.
trap "rm -f in.$$" 0 1 2 3 15
# Start processing.
cd $INSPECT_DIR || { echo $INSPECT_DIR does not exist; exit
$EX_TEMPFAIL; }
cat >in.$$ || { echo Cannot save mail to file; exit $EX_TEMPFAIL; }
/usr/bin/altermime --input=in.$$ \
--disclaimer=/home/filter/stopka.txt \
--disclaimer-html=/home/filter/stopka.html \
$SENDMAIL "$@" <in.$$
exit $?

Hi there,
I was doing a research about how to implement an outgoing email filter.
For every sent message we want to add a footer with a counter.
I've tried to add the "content_filter" tag as shown:
smtp inet n - n - 50 smtpd
-o content_filter=footer
footer unix - n n - - pipe
flags=Rq user=myuser argv=/home/postfix/tag.sh ${sender}
${recipient}
But the messages doesn't seem to be filtered.
$ postconf | grep content_filter
content_filter = (empty)
Is this supposed to work? Is there a workaround for this?
Huge thanks.
