I am attempting to setup the external cronjob to run every 2 minutes, but it doesn't seem to be gathering up any mail. When I manually run "/usr/bin/php /path/to/api/cron.php (with the path fixed)" it just prints out a blank line, and while watching the mail logs (on a different server), I can see that it never logs in to do anything.
Crontab entry: */2 * * * * nobody /usr/bin/php /path/to/api/cron.php
Any ideas?
