My Verizon/AOL email is being rejected by a forwarding feature in a travel app wherein I forward a flight confirmation to the app email address that in turn, forwards it to the mobile app backend. The travel app uses GoDaddy and their support has said it has to do with the DMARC related to my Verizon/AOL email that prevents it from processing through the GoDaddy forwarding. The problem looks similar to this old issue:
