        Our company integrates third party sign ins (e.g. Facebook) so we have added support for Sign in with Apple as well. However, when testing emails sent from our registered domains (verified on developer.apple.com) the emails are bouncing with the error code "550 5.1.1 bad mailbox name". Our domain is verified and our emails are sent using SendGrid from those domains.


        Do you have a timeline on when 3rd party email services will be supported? If it's after the public release of iOS 13, can we get confirmation on whether or not the next version of our app must support Sign in with Apple to be approved?
