I agree. A good auto-responder should detect messages from a list. Our
autoresponders are using .mailfilter. In it I have this:

RECIPIENT=$LOGNAME
RESPOND="~/.vacation.msg"
RESPONDDB="~/.vacation.db"
if ( ! /^Precedence: (bulk|list|junk)/ && \
     ! /^List-Id:/ && \
     ! /^List-Unsubscribe:/ && \
     ! /^Return-Path:.*<#@\[\]>/ && \
     ! /^Return-Path:.*<>/ && \
     ! /^From:.*MAILER-DAEMON/ && \
     ! /^X-ClamAV-Notice-Flag: *YES/ && \
     ! /^Content-Type:.*message\/delivery-status/ && \
     ! /^Subject:.*Delivery Status Notification/ && \
     ! /^Subject:.*Undelivered Mail Returned to Sender/ && \
     ! /^Subject:.*Delivery failure/ && \
     ! /^Subject:.*Message delay/ && \
     ! /^Subject:.*Mail Delivery Subsystem/ && \
     ! /^Subject:.*Mail System Error.*Returned Mail/ && \
     ! /^X-Spam-Flag: YES/ )
{
        cc "| mailbot -t $RESPOND -d $RESPONDDB -D 1 -A 'From:
$RECIPIENT' -s 'Auto Response: from $RECIP
IENT' /usr/sbin/sendmail -t"

}

which I believe is enough to NOT send bounce messages. In the case of
MLMMJ, it will match the List-Id: header.

Has any of you other header types that my autoresponder should match?
Did we miss some?
