When clicking "Don't have a login? Create an account" and filling out the form and click ADD button, SMTP error occurs.

Solution:
PHP mailer
1. make user that IIS supports php function
http://localhost/test.php
test.php
<?php phpinfo(); ?>
2. copy class.phpmailer.php,class.pop3.php, and class.smtp.php from TCExam\shared\phpmailer directory into the website's homedirectory

3.
Because a static IP address is assigned from Shawcable, I could use the port 25 directly.
Save the following code to a.php file and test it.
require("class.phpmailer.php");
$mail = new PHPMailer();
$mail->IsSMTP();
$mail->Host = "shawmail.vc.shawcable.net";
$mail->SMTPAuth = false;
$mail->AddAddress("kaiming.liao@gmail.com");
$mail->AddAddress("kmliao@hotmail.com");
$mail->Subject = "Test 1";
$mail->Body = "Test 1 of PHPMailer.";
$mail->From="kaiming@vanarts.com";
$mail->FromName="mailer test";
$mail->Sender="kaiming@vanarts.com";
$mail->AddReplyTo("kaiming@vanarts.com","Replies for my site");
$mail->AddAttachment('c:\nic.bmp');
if(!$mail->Send())
{
echo "Error sending: " . $mail->ErrorInfo;;
}
else
{
echo "Letter is sent";
}?>
Confirmation email can be sent out.
4. POP before SMTP Authentication
<?php
require("class.pop3.php");
$pop = new pop3();
$pop->Authorise('mail.vanarts.com',110,30,'kaiming@vanarts.com','password',1);
require("class.phpmailer.php");
$mail = new PHPMailer();
$mail->IsSMTP();
$mail->Host = "mail.vanarts.com";
$mail->SMTPAuth = false;
$mail->AddAddress("kaiming.liao@gmail.com");
$mail->AddAddress("kmliao@hotmail.com");
$mail->Subject = "Test 1";
$mail->Body = "Test 1 of PHPMailer.";
$mail->From="kaiming@vanarts.com";
$mail->FromName="mailer test";
$mail->Sender="kaiming@vanarts.com";
$mail->AddReplyTo("kaiming@vanarts.com","Replies for my site");
if(!$mail->Send())
{
echo "Error sending: " . $mail->ErrorInfo;;
}
else
{
echo "Letter is sent";
}?>
Confirmation message can be sent out.
Who sends the message out?
