Purpose ======= When a public user fill a form on Website (e.g. /contactus), an email will be sent. The email filled in the form will be used as the "email from", but if no mail server match this email address it will be encapsulated into "`notifications@mycompany.com`" (see odoo/odoo#61853). Even though the email is still present in the "Reply-To" header, we want to add it at the end of the email, so the receiver has this information easily.
