使用GMail SMTP服务器从PHP页面发送电子邮件

Question

我正在尝试从PHP页面通过GMail的SMTP服务器发送电子邮件，但出现此错误：

身份验证失败[SMTP：SMTP服务器不支持身份验证（代码：250，响应：mx.google.com，为您提供服务，[98.117.99.235]大小为35651584 8位MIME STARTTLS增强的状态代码，编码方式）]]

有人可以帮忙吗？这是我的代码：

<?php
require_once "Mail.php";

$from = "Sandra Sender <[e-mail]>";
$to = "Ramona Recipient <[e-mail]>";
$subject = "Hi!";
$body = "Hi,\n\nHow are you?";

$host = "smtp.gmail.com";
$port = "587";
$username = "[e-mail]";
$password = "testtest";

$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>");
 }
?>

// Pear Mail Library
require_once “Mail.php”;

$from = '<[e-mail]>';
$to = '<[e-mail]>';
$subject = 'Hi!';
$body = "Hi,\n\nHow are you?";

$headers = array(
    'From' => $from,
    'To' => $to,
    'Subject' => $subject
);

$smtp = Mail::factory('smtp', array(
        'host' => 'ssl://smtp.gmail.com',
        'port' => '465',
        'auth' => true,
        'username' => '[e-mail]',
        'password' => 'passwordxxx'
    ));

$mail = $smtp->send($to, $headers, $body);

if (PEAR::isError($mail)) {
    echo('<p>' . $mail->getMessage() . '</p>');
} else {
    echo('<p>Message successfully sent!</p>');
}
