Fix to Prestashop contact form not sending email to shop owner

We have two prestashop stores hosted on same server. Two Prestashop versions: - 1.4 - 1.3.2 In both cases, the prestashop contact form is not sending email to us (store owners) or, at least, we are not receiving it. Prestashop is using PHP mail() function in both stores. Prestashop tries to send these emails as appearing to be sent from the customer's email address. If we enter the store's email address into the contact form email address field then the form works fine, the email is received. This seems to be a case of SMTP rejecting the relay because of the FROM email address domain is not hosted on that server. THE PROJECT Modify PHP code for the contact form on both stores so that the FROM address is the store's email address, not the customer's, and the customer's email address is included in the body of the email. ---------------- (If you are an expert on WHM and SMTP configuration and you know how to solve this problem by modifying the SMTP configuration, please post your offer too, with a note to tell us that you would be modifying SMTP configuration) Thank you Juan
