Can you tell me which file generates the lines in the .autoresponder file
cc "| mailbot -t $RESPOND -d $RESPONDDB -c 'UTF-8' -D 1 \
-A 'From: $RECIPIENT' -s 'Auto Response: from $RECIPIENT' \
/usr/sbin/sendmail -t -f ''"
From there mailbot can be substituted for the basic mail/mailx command to send out the autoreply only back to the user instead of trying to change the reply order. Ultimately it's auto response we want to be highlight ... I don't think anyone needs to have the original email echoed back to them.
