In Totara learn v 13, we cleared out all the users and had everyone that was still around to self register. All of them were automatically subscribed to the forum. We we send out a message it sends about 150 out of 450 out. Something is going right as 150 do go out and 98.5% get delivered. So why is it truncating. I know users can unsubscribe but I clearly doubt so many did so as the messages are infrequent, short and very important to the user base.
We're running out of ideas as to where to look. The cron runs just fine. The SMTP settings must be good since the messages do go out to 150. We're pulling our hair out here. If anyone can please give us ideas of anything we should take a look at, we would be very grateful for your help.
Thanks, Diane
