We are wishing to have all EasyDiscuss notifications sent only from one email; instead of it appearing as an email from the student.

For instance, all from me as the webmaster rather than everyone.
As we noticed a tremendous amount of emails going into spam because of new and unrecognizable emails.
Also, a few members have already raised their voices about their information being sent to other subscribers when posting.

Is there a setting option that makes this possible?

I see, I've helped you disabled this setting Modify Sender Details to User Details so the system will not modify the sender email address now.

Also, we can't control why some of the email notifications will go to the junk mailbox, since you have using SMTP mailer, perhaps you can consult with your mailer administrator and see if possible to investigate this?

The user needs to set their subscription interval to daily or weekly so the system will not keep sending a new reply/question instantly.

If the user sets their subscription interval to instant, mean they want to get the email notification instantly when the discussion post has a new reply or question.

Yes, thanks I think I confused even myself, as I just placed it as instant to test and ensure that everyone had been receiving emails from users from the site and not just the admin.. But again, the disabling did exactly what I tried so hard to explain, but failed...

Thanks for decoding this support ticket
