以下代码在xampp1.7.3中工作，但在xampp1.7.7中不工作

authentication failure [SMTP: SMTP server does not support authentication (code: 250, response: mx.google.com at your service, [59.92.73.34] SIZE 35882577 8BITMIME STARTTLS ENHANCEDSTATUSCODES)]

这是一个邮件程序

<?php
 require_once "Mail.php";
        $from = "username@gmail.com";
        $to = "username@gmail.com";
        $subject = "Hi!";
        $body = "Hi,\n\nHow are you?";
        $host = "smtp.gmail.com";
        $port = "587";
        $username = "username@gmail.com";
        $password = "pwd";
        $headers = array ('From' => $from,
          'To' => $to,
          'Subject' => $subject);
        $smtp =@ Mail::factory('smtp',
          array ('host' => $host,
            'port' => $port,
            'auth' => true,
            'username' => $username,
            'password' => $password));
        $mail = @$smtp->send($to, $headers, $body);
        if (@PEAR::isError($mail)) {
          echo("<p>" . $mail->getMessage() . "</p>");
         } else {
          echo("<p>Message successfully sent!</p>");
         }
?>

这个错误会有什么问题，请给出您的建议。

如果我使用端口号465代码添加ssl加密，它会引发一些其他错误

首先，smtp.gmail.com侦听端口465，使用ssl加密，我在您的代码中看不到这一点。如果我添加端口号为465的ssl加密，它会引发一些其他错误。您需要联系主机提供商以了解该错误。

Failed to connect to ssl://smtp.gmail.com:465 [SMTP: Failed to connect socket: Unable to find the socket transport "ssl" - did you forget to enable it when you configured PHP? (code: -1, response: )]
