先附上PHPMailer下载地址：https://github.com/VisionZheng/PHPMailer
使用方法：
```php
<?php
$rootPath = dirname(__FILE__);
require $rootPath.'/PHPMailer/PHPMailerAutoload.php';
$mail = new PHPMailer;
// 调试模式，可以看到哪里出现错误
//$mail->SMTPDebug = 3; // Enable verbose debug output
$mail->isSMTP(); // Set mailer to use SMTP
$mail->Host = 'smtp.aliyun.com'; // Specify main and backup SMTP servers
// 是否需要验证
$mail->SMTPAuth = true; // Enable SMTP authentication
// 邮件内容编码
$mail->CharSet = 'UTF-8';
$mail->Username = 'vision@aliyun.com'; // SMTP username
$mail->Password = '********'; // SMTP password
// $mail->SMTPSecure = 'tls'; // Enable TLS encryption, `ssl` also accepted
$mail->Port = 25; // TCP port to connect to
// 设置发件人
$mail->setFrom('visionz@aliyun.com', 'visionz');
// 设置收件人，可以有多个，多个在同样的加
$mail->addAddress('1092161320@qq.com', 'asdfasdfasf'); // Add a recipient
// $mail->addAddress('ellen@example.com'); // Name is optional
// 回复给哪个邮箱
$mail->addReplyTo('visionz@aliyun.com', 'visionz');
// 抄送给谁
// $mail->addCC('cc@example.com');
// $mail->addBCC('bcc@example.com');
// 附件
// $mail->addAttachment('/var/tmp/file.tar.gz'); // Add attachments
// $mail->addAttachment('/tmp/image.jpg', 'new.jpg'); // Optional name
// 正文是否有加HTML标签
$mail->isHTML(true); // Set email format to HTML
$mail->Subject = 'Here is the subjectdfdfdfd';
$mail->Body = 'This is the HTML message body <b>in bold!</b>';
// 直接发送HTML文件里的内容
// $mail->msgHTML(file_get_contents($rootPath."/sendmail.html"));
// 没有带HTML的内容
// $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';
if(!$mail->send()) {
echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
echo 'Message has been sent';
}
```
