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