不会PHP，这个好象是“收发”邮件的一个程序，估计是好东西。

if ($EMAIL_INC) return;
$EMAIL_INC=    "defined";
define( "SmtpPort",25);
class Pop3 {
    var $subject;             // 邮件主题    
    var $from_email;               // 发件人地址
    var $from_name;              // 发件人姓名
    var $to_email;               // 收件人地址
    var $to_name;             // 收件人姓名
    var $body;              // 邮件内容
    var $filename;               // 文件名
    var $socket;            // 当前的 socket
    var $Line;
    var $Status;
    function pop3_open($server, $port)     
    {
        $this->Socket = fsockopen($server, $port);
        if ($this->Socket <= 0){
       return false;
        }
    $this->Line = fgets($this->Socket, 1024);
    $this->Status[ "LASTRESULT"] = substr($this->Line, 0, 1);
    $this->Status[ "LASTRESULTTXT"] = substr($this->Line, 0, 1024);
