Hi,
Thank you for your response,
unfortunately, it didn’t work
this is my code for sending mail
if (mail($mailto, $subject_from_web, $message_fromCustomer, $header_ToWebOwner)&& mail($from, $subject_confirmation, $message_AutoReplay_ToClient, $headers_ToClient)) {
header('Location: contactez-nous.php?CaptchaPass');
echo '<script type="text/javascript">successFunction("Message was sent successfully, check your emails!");</script>';
} else {
echo '<script type="text/javascript">failedFunction("Mail was not sent, Try again!.");</script>';
}
