This comes up from time to time. I think the consensus was to simply
generate your own bounce message.
(Or use procmail as MDA in sendmail.cf).
Does this translate to: if you want to bounce a message without exposing
.forward, you have to do it yourself with formail?
Well then, I have created a recipe which emulates EXITCODE=77, and it
works fine, except for two details.
Bounced messages on our system are MIME-encoded and have the following header:
Content-Type: multipart/mixed; boundary="SAA09016.870370791/host"
I seem unable to put in the "'s. formail called with
-A"Content-Type: multipart/mixed; boundary=\"SAA09016.870370791/host\""
doesn't work, ie. the \" in the argument to -A. The logs tell me
Unmatched ".
What can I do? It works without the \"'s, but then I get only
Content-Type: multipart/mixed; boundary=SAA09016.870370791/host
Here is the full recipe, with a description of the second problem
embedded. This is all with procmail 3.11pre7 on SunOS 4.1.3 and
Solaris 2.5.1.

# still testing ...
* ^Subject.*bounce test
* ^From.*me
* !^X-Loop: me(_at_)address

# First: save the full message
:0c:
# TEMPORARY=/tmp/pmail.$$
${TEMPORARY}

echo "The original message was received at ${BOUNCEDATE}" ; \
echo "from {USER(_at_)HOST [IP]}" ; echo "" ; \
# The second problem: how do I get USER(_at_)HOST [IP]?

cat ${PMDIR}/bounce.msg ${TEMPORARY} ${PMDIR}/bounce.tail ; \
) | $SENDMAIL -t
}
Thanks for any insights.
