Ok since you are all so convinced it has no disadvantages: I rewrote
Henning Brauwers qsecretary-autoreply scripts so they support/use procmail.


First of all let your MTU use qsecretarywrapper when mailing to the
qmail list:

For mutt that would be:

  folder-hook qmail set sendmail="~/.mutt/qmailsecretarywrapper"


This is the qmailsecretary wrapper script:

  #!/bin/sh
  auth=`dd if=/dev/urandom ibs=6 count=10 2>/dev/null | sha1`
  touch ~/tmp/$auth
  export QMAILINJECT=i
  ( echo "X-qs-auth: $auth" ; cat ) | /var/qmail/bin/qmail-inject $*


Next in line comes .qmail which has to contain:

  |preline -f /usr/local/bin/procmail


Then you should add this recipy to your .procmailrc:

  :0
  * ^From. "The qsecretary program" \<list-qmail-notbulkmail-[0-9a-f]*@list\.cr\.yp\.to\>
  | ~/.mutt/qmailsecretaryreply


And finally there is the qmailsecretaryreply-script:

  #!/bin/sh
  RECIPIENT=`/usr/local/bin/822field from | cut -d"<" -f2|cut -d">" -f1`
  AUTH=`cat | grep \^X-qs-auth: | sed 's/^X-qs-auth: \([a-f0-9]*\)/\1/'`

  if [ -f ~/tmp/$AUTH ]; then 

  	  rm ~/tmp/$AUTH
	  echo "Mellon" | mail $RECIPIENT 

  else 

	  echo "Someone is trying to forge something I think" | mail `whoami`

  fi


I keep a copy of those script and settings on:
