I have read about and am realized that order-related emails are now queued up in the database instead of being sent out directly in CE 1.9.1.0.
I have installed two magento's onto two different servers, both of which are CE 1.9.1.0. And I have not configured the cronjobs for any of them. One of them behaved just as described in the release note. I could find new records in the table core_email_queue. However, for the other one, emails were sent out immediately without any records created in the table core_email_queue.
Actually, the one that "bypassed" the email queue was not installed and configured by me. So I wonder how I could find out why they behaved differently, given that no classes have been overridden in both magento's.
Thank you in advance.
