首先，建立一个index.html文件，代码如下：
simple send ma...</div>

<p>首先，建立一个index.html文件，代码如下：</p>
<div class="jb51code">
<pre class="brush: php;">
<html>
<head>
<title>simple send mail </title>
</head>
<body>
<h1>mail form</h1>
<form name="form1" method="post" action="mail.php">
<table>
<tr><td><b>to</b></td><td>
<input type="text" name="mailto" size="35">
</td></tr>
<tr><td><b>subject</b></td>
<td><input type="text" name="mailsubject" size="35"></td>
</tr>
<tr><td><b>message</b></td>
<td>
<textarea name="mailbody" cols="50" rows="7"></textarea>
</td>
</tr>
<tr><td colspan="2">
<input type="submit" name="submit" value="send">
</td>
</tr>
</table>
</form>
</body>
</html></pre>
</div>
<p>然后新建一个“mail.php”文档把传输的文档进行发送</p>
<div class="jb51code">
<pre class="brush: php;">
<?php
$stm="邮件内容";
require("smtp.php");
##########################################
$smtpserver = "smtp.qq.com";//smtp服务器
$smtpserverport = "465";//smtp服务器端口
$smtpusermail = "xxx@qq.com";//smtp服务器的用户邮箱
$smtpemailto = "aaa@qq.com";//发送给谁
$smtpuser = "xxx@qq.com";//smtp服务器的用户帐号
$smtppass = "666";//smtp服务器的用户密码
$mailsubject = "666 ";//邮件主题
$mailbody = $stm;//邮件内容
$mailtype = "html";//邮件格式（html/txt）,txt为文本邮件
##########################################
$smtp = new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass);//这里面的一个true是表示使用身份验证,否则不使用身份验证.
$smtp->debug = true;//是否显示发送的调试信息
$smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype);
echo "<script>alert('邮件发送成功');parent.document.adduser.cheheh.click();</script>";
exit;

<p>最后编写一个邮件类“smtp.php”</p>
