We use Sign in with Apple. Emails to @privaterelay.appleid.com bounce with "550 5.1.1 <...@send-subdomain>: unauthorized sender" for 4+ days.
Setup:
- Sending via Resend (Amazon SES, eu-west-1)
- From: siparis @ truefriends.com.tr, envelope: send.truefriends.com.tr
- All four Email Sources show green SPF in Certificates, IDs & Profiles:
- truefriends.com.tr (Domain)
- send.truefriends.com.tr (Domain)
- siparis @ truefriends.com.tr (Email)
- *@send.truefriends.com.tr (Email wildcard) — added today, no effect
- Test mail to non-Apple inbox: spf=pass, dkim=pass (d=truefriends.com.tr matches From), dmarc=pass. So full authentication is verified.
Filed Feedback Assistant + Developer Support case 102902232938 — Tier 1 deflected to Feedback. Waiting for engineering response.
Has anyone resolved a case where portal shows green ✓ but Relay still rejects as unauthorized? Internal sync issue?
