I've created a sending and bounce domain on Sparkpost, ccrmmail.vietfeir.com. This domain has been verified by Sparkpost. I have an api key with all grants. When I try to save and send, I get this error:
Could not check status for domain vietfeir.com (Exception Sparkpost error: Permission denied. Check that the API key is authorized for request https://api.sparkpost.com/api/v1/sending-domains/vietfeir.com.).
How can I configure this correctly to use ccrmmail.vietfeir.com instead of just vietfeir.com?
