How to send emails to users with Apple social login with masked email address

Dear Auth0 Community,

We’re trying to send operational emails to our valued customers using AWS SES, while since we use Auth0 social login so most of the user’s emails are masked as xxx@privaterelay.appleid.com if they login with Apple. Our email delivery just get bounced with these mails. We already configured in Apple Developer console and AWS side, so we want to know what else are we missing.

The error message on SES side is like:

---
Action: failed
Final-Recipient: rfc822; xxx@privaterelay.appleid.com
Diagnostic-Code: smtp; 550 5.1.1 <01060192e65fc94c-e3ac2ecf-6211-4abc-8929-8c1f2d5328f9-000000@{{our mailer domain}}>: unauthorized sender
Status: 5.1.1

Thank you for your help in advance!

Hi @min ,

Can you confirm you followed all of the steps outlined here: Configure Amazon SES as External SMTP Email Provider

Can you successfully send yourself a test email by clicking the “Send test email” button? Do you have any tenant logs for email delivery failures (log type fn)?

Additionally, here is a Community post describing an issue with Amazon SES and emails not being sent: When Using Amazon SES, Emails are not Being Sent

I look forward to your reply!

Best,

Mary Beth
