Goal I want to reply to feedback from customers who signed up using a private.relay account. Problem I am getting this error when sending an email: Reporting-MTA: dns; mailfout.stl.internal X-Postfix-Queue-ID: B87481D0015B X-Postfix-Sender: rfc822; hello@mydomain.com Arrival-Date: Fri, 7 Nov 2025 03:37:29 -0500 (EST) Final-Recipient: rfc822; xxxx@privaterelay.appleid.com Original-Recipient: rfc822;xxxx@privaterelay.appleid.com Action: failed Status: 5.1.1 Remote-MTA: dns; smtp3.privaterelay.appleid.com Diagnostic-Code: smtp; 550 5.1.1 <hello@mydomain.com>: unauthorized sender What have I done? I have configured mydomain.com in the Email Configuration Service inside of apple, as well as the email hello@mydomain.com. Using https://www.mail-tester.com/, I could confirm that the - [SPF] Your server 202.12.124.158 is authorized to use hello@mydomain.com - Your DKIM signature is valid - Your message passed the DMARC test My hunch This app was transferred and the previous owner did not have the email configuration set up. The emails I am writing messages to signed up at that time. Questions: If I rescue the old account and set up the email configuration, would it work? Is there any other tip I could try to apply?

Several users have reported that my iOS Action and Share Extensions is not visible. Now one of the TestFlight users has reported the same. Notice this user has been using the app for one year, so they know how to use it. Doing FaceTime and them sharing the screen, we have tried: Deleting app and downloading from App Store Deleting app, turning device off (call was off) and turning it on, downloading from App Store Deleting app, turning device off (call was off) and turning it on, downloading from TestFlight They can open the app, they just do not see the extensions. I would have thought it was the activation rules inside of the InfoPlist, but they are the same for all users and my other testers are not facing the issue. Device is iPhone 16 Pro, iOS 18.1 What other steps could I follow? What other information could I gather to fix this?
