Ask for questions about sending mail to a PHP environment that you set up under Windows XP

Ask for questions about sending mail to your PHP environment under Windows XP!
I want to use my own PHP test environment under XP to test PHP's own mail function, I do a local hosts mapping a fake domain name, installed a winwebmail SMTP server, do not know why is sent unsuccessful, do not know what is going on. The PHP code is as follows
$mailTo = "xxxxx@qq.com";
$mailSubject = "Just a test mail!";
$mailBody = "This is a test of PHP ' s mail function.";
$mailBody. = "It is generated by PHP version.";
$mailHeaders = "From:admin@system.mail";
$a = Mail ($mailto, $mailSubject, $mailBody, $mailHeaders);
if ($a)
{
echo "Mail uccessfully sent!";
}
Else
{
echo "Error in sending mail!";
}
?>
Can the gods enlighten you?
