   4     * Utility to debug mailouts - will save the content of emails to a
   5     * logfile instead of sending them out. Use it as a sendmail
   6     * "stand-in" when testing mailouts.
   7     *
   8     * It is not Moodle specific - use it anywhere by setting the php
   9     * "sendmail_path" setting to this file with a logfile parameter.
  10     *
  11     * - Set in php.ini (not settable in config.php):
  12     *     sendmail_path=/path-to-moodle/admin/mailout-debugger.php');
  13     *   Or from the commandline
  14     *     php -d sendmail_path='/path-to-moodle/admin/mailout-debugger.php' /path/to/cron.php
  15     *
  16     * - Create a file in admin called mailout-debugger.enable
  17     *   (this is a security check to prevent execution in prod environments)
  18     *   touch /path/to/moodle/admin/mailout-debugger.enable
  19     *
  20     * - Mark as executable: chmod ugo+rx mailout-debugger.php
  21     *
  22     * - Run your admin/cron.php
  23     *
  24     * - Read /tmp/moodle-mailout.log
  25     *
  26     *
  27     * This script will create logfiles in /tmp/ or in $TMPDIR if set.
  28     * On windows, use php -r 'print sys_get_temp_dir()' to see where the file is saved.
