Hi, I’d like to contribute to resolving this issue. The missing Reply-To and Reply-To Name headers can be addressed by modifying the email generation logic in the contact form’s backend code. My plan involves:

Extracting the Reply-To email and name from the contact form.
Adding these values to the email headers using the Mailer class.
Ensuring backward compatibility and handling edge cases (e.g., empty or malformed Reply-To fields).
I’ll also test the changes with PHP 8.3 to ensure compatibility. Let me know if this approach aligns with the project’s goals, and I’ll start working on it.
