hot to allow a blocked Email-adress
I want to receive Emails from an app I use. I activated there through another Emailadresse, since now Email arrived at my mailbox.org account. Now I want to change the Email-address but still no email reaches my mailbox.org Inbox/Spam. I also switched greylisting off, but still no sucess.
How can I allow the firstname.lastname@example.org address?
Thank you for your help
