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.
