Perhaps with smtp_generic_maps, but not with canonical
maps because that happens before the queue.

Thank you.
By now I'm trying to implement a content filter to change some headers
of the received message. To do that, I added a service to the master.cf
file:
external unix - n n - - pipe
flags=Fq user=user:user argv=/opt/scripts/external.sh ${recipient}
The script is a very simple bash script that replaces the 'From' header:
#!/bin/bash
content=$(cat)
contfin=$(sed 's/From: r...@original-domain.com/From:
r...@modified-domain.com/' <<< "$content")
TMPFILE=`mktemp`
echo $contfin > $TMPFILE
cat $TMPFILE | /usr/sbin/sendmail -G -i -f r...@modified-domain.com
-- $1
/bin/rm -f $TMPFILE
exit $?
In transports map file (postmapped):
destinar...@user.com external:
The script seems to do what it should, however, in the Postfix logs it
seems to loop, like the message was put in the queue again and passed to
the queue over and over (and the message never arrives):

How can I avoid this behavior? Once the message is modified I'd like to
send it without passing it again to the filter.
Thanks again.
