I have a contact form setup on my external non-odoo website that sends emails to my odoo help desk. The 'from' email address is no-reply@mydomain.com and not the customers email so in the help desk the customer name and email are not correct. The customers name and email are in the body of the first email sent to the help desk.  Is it possible to retrieve the first message sent to the helpdesk in the create method in helpdesk_ticket.py?
