When you see header issues despite domain verification:

1. Authentication Check:

• Verify all authentication methods (SPF, DKIM, and DMARC) are passing

• Check Return-Path alignment with From domain

• Ensure DKIM signatures are valid and using correct selectors

2. Common Issues:

• Mismatched sending domains

• Incorrect authentication record implementation

• Missing or incorrect DKIM keys

• Sending configuration issues in your Email account

For specific header issues, check your Email dashboard or contact Email support with the full headers for detailed analysis.
