主要是编码的问题:
解决办法就是: 读取的数据设置好编码方式； 发邮件的时候也指定编码方式；
先用函数base64_encode() 使用 mime base64 对数据进行编码
标题字符串前加编码类型例如： =?utf-8?b?
当然如果是gb2312的话就 =?gb2312?b?
标题字符串后加：?=

<html>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<body>
<?php
if(strlen($_post["from"]) > 1)
//if "email" is filled out, send email
{
//send email
$email = $_post["from"] ;
$mailto = $_post["mailto"];
$subject = "=?utf-8?b?" . base64_encode($_post["subject"]) . "?=";
$message = $_post["message"] ;
$header = 'mime-version: 1.0' . "\r\n"
. "content-type: text/html; charset=utf-8". "\r\n"
. "from: <$email>"."\r\n";

mail("$mailto", "$subject", $message, "$header" );
