Use the following format for the cron definition:
/usr/local/bin/php /path/to/your/a/a.php cli/auto
/usr/local/bin/php /usr/www/users/yourname/~domaindirectory/a/a.php cli/auto
Change yourname and ~domaindirectory to suit your hosting account. To know the absolute path to the a.php script, log in to your arpReach system and go to Help / About... / System.
This host does not have email catch-all functionality.
