<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>

然后新建一个“mail.php”文档把传输的文档进行发送

$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;

}

?>

最后编写一个邮件类“smtp.php”
