Domain Email Authentication Setup

Scenario

A developer configures their domain's DNS records (SPF, DKIM, DMARC) to authenticate both Resend for transactional application emails and Alibaba Mail for corporate communication on the same domain, coordinating records so both services send legitimately without delivery failures.

How the products combine

1. alimail · alimail-configure-communication — Alibaba Mail — Set up secure email communication

See alimail/alimail-configure-communication.

2. resend · resend-verify-domain — Resend — Verify a sending domain for email authentication
