We are using Moodle 3.3.
After posting to a topic to a discussion forum with the instruction to send out the email alert to the subscribed users immediately, the email alert arrived 48 minutes later, which is much too late.
I posted another topic to the discussion forum with NO instruction for immediate email alert. In this case, the email alert arrived 80 minutes later, which is much later than the supposed 30 minutes.
These two problems have occurred more than once.
I wonder if we need to set some correct parameters on our Moodle system to rectify these two delay problems. We have a dedicated server running Moodle and it should be free to send out email alerts at any time, so the problems are not to do with a slow server.
Your help will be much appreciated.
