I have enabled the public "Activate the public portal (company news, jobs, contact form, etc.)".

When I send an test message (logged in as newly created user, and not logged in) from the "About Us" -> "Contact us" form, I get the message "Thank you for your interest, we'll respond to your request shortly.".

But there is only created an record (content is missing) in as "System notification" / "Document created" in settings->E-mails->Messages (Related Document Model: portal_crm.crm_contact_us).

What do I have to do to let the form result send an email to an given email address?
