Here is my setup: INIZ VPS Centmin Mod Magento 18.104.22.168 My cronjobs are running fine. I have installed AOE Scheduler which says that scheduling and cron heartbeats are working fine. However, my order emails are not being sent. In the 'List View' of AOE Scheduler the message area in front of the 'core_email_queue_send_all' job shows '---RETURN_VALUE--- Mage_Core_Model_Email_Queue'. I don't know if that's an error or its normal. Basically, I have no idea why the emails are not being sent despite crons being working fine. I suspect that it might be something related to Centminmod or the server which is not sending the emails. Any help in tracking down the issue will be highly appreciated.
