Updated Behavior for Dedicated Domain Default Header Fallback

✅ What’s New

Previously, the Dedicated Header (From Name and From Email) was always used as the primary identity when sending emails through a dedicated domain.

With this update, we’ve changed how and when this header is applied:

🆕 Changes Introduced

1. Fallback Header Activation Only on DMARC Failure - The dedicated header will now only apply when DMARC alignment fails (based on SPF/DKIM logic).

2. Fallback Triggered When No Custom Header is Provided - If users do not specify a custom "From Name" or "From Email", and DMARC fails, the system will automatically apply the fallback header.
