Mailgun issue (not sending emails)

So I have everything set-up. I’m getting all my emails but when someone else tries registering or performing an administrative action, such as granting permissions or backing up the server, they’re not receiving their emails. I checked my mailgun logs and it’s fine with sending emails to me, but when it shows someone else’ email it’s marked as rejected.
