<?php
require 'class.phpmailer.php';
try {
  $mail = new PHPMailer(true);
  $body = file_get_contents('contents.html'); //邮件的内容写到contents.html页面里了
  $body = preg_replace('//////','', $body); //Strip backslashes
  $mail->IsSMTP(); // tell the class to use SMTP
  $mail->SMTPAuth  = true; // enable SMTP authentication
  $mail->Port = 25; // set the SMTP server port
  $mail->Host = "mail.yourdomain."; // 远程SMTP服务器
  $mail->Username = "yourname@yourdomain."; // 远程SMTP 服务器上的用户名
  $mail->Password  = "yourpassword"; // 你的远程SMTP 服务器上用户对应的密码
  //$mail->IsSendmail(); //告诉这个类使用Sendmail组件，使用的时候如果没有sendmail组建就要把这个注释掉，否则会有
  $mail->AddReplyTo("yourname@yourdomain.","First Last");
  $mail->From    = "fromname@yourdomain.";
  $mail->FromName  = "First Last";
  $to = "toname@domain.";
  $mail->AddAddress($to);
  $mail->Subject = "First PHPMailer Message";
  $mail->AltBody = "To view the message, please use an HTML patible email viewer!"; // optional, ment out and test
  $mail->WordWrap = 80; // set word wrap
  $mail->MsgHTML($body);
  $mail->IsHTML(true); // send as HTML
  $mail->Send();
  echo 'Message has been sent.';
} catch (phpmailerException $e) {
  echo $e->errorMessage();
}
?>
