   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.
