I’ve just fixed this problem in contact with my hosting provider editing the contact.php file, changing a “From” header for a “Reply-to” header:
$headers = ‘Reply-To: ‘ . $name . ‘ <‘ . $email . ‘>’ . “\r\n”;
if ($evolve_sent_email_header) {
$headers .= ‘From: ‘ . $emailFrom . ‘ <‘ . $email . ‘>’ . “\r\n”;
} else {
$headers .= ‘Reply-To: ‘ . $emailTo . ‘ <‘ . $email . ‘>’ . “\r\n”;
Hope this solution can help somebody else.
