I've got a Magento 1.9.1 implementation and am having issues sending out order related emails.
I have checked cron jobs and AOE Scheduler reports core_email_queue_sendall and core_email_queue_cleanup are enabled and running.
I've setup system cron to run cron.php every 5 minutes.
But I'm still not receiving emails.
Upon checking the database tables, I actually see that all the order related emails (new orders, etc) are in core_email_queue. The 'processed_at' column has a value, indicating that the email has been processed.
Why don't I see the emails? Does having a 'processed_at' value indicate that the emails had already been sent out?
