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.
You need to validate your domain at Mailgun.
How can I go about doing this?
It’s requiring a credit card which I don’t have one, is there a free, unrestricted alternative?
There is not. Because spam.
Okay, thank you for the help.
