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 220.127.116.11.
I have installed two magento's onto two different servers, both of which are CE 18.104.22.168. 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
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.
