For my monthly typing-injury FAQ, which is sent to three LISTSERV's, my posting
script appends the current date to the end of the FAQ, e.g.:
echo "To: [log in to unmask]" > $tmpfile
cat $faq >> $tmpfile
echo -n "Mailing date: " >> $tmpfile
date >> $tmpfile
/usr/lib/sendmail -t < $tmpfile
This handily defeats the checksum mechanism.
