Hi,
When you click on the "+" signs in your spam report it will show you what's wrong.
You can't send mails with your orange.fr mailadres straight from your server because it does not match your domain name. When you want to keep using your orange.fr mail address you should configure Acymailing to send the mail through a smtp-server that belongs to orange.fr.
You might want to consider to start using a mail address that matches the domain you are sending from. It gives you much more credability.
