+# The command used to send mail, which uses the above options
+# can be modified. By default if the mailer is "sendmail" then
+#  MAIL_COMMAND = echo \'Subject: $SUBJECT\n\n$MESSAGE\' | $MAIL_PATH/$MAILER -t $MAILTO
+# For mail or mailx:
+#  MAIL_COMMAND = "$MAIL_PATH/$MAILER -s \'$SUBJECT\' $MAILTO <<< \'$MESSAGE\'
+# ktest.pl will do the substitution for MAIL_PATH, MAILER, MAILTO at the time
+#    it sends the mail if "$FOO" format is used. If "${FOO}" format is used,
+#    then the substitutions will occur at the time the config file is read.
+#    But note, MAIL_PATH and MAILER require being set by the config file if
+#     ${MAIL_PATH} or ${MAILER} are used, but not if $MAIL_PATH or $MAILER are.
+#MAIL_COMMAND = echo \'Subject: $SUBJECT\n\n$MESSAGE\' | $MAIL_PATH/$MAILER -t $MAILTO

 # Errors are defined as those would terminate the script
