如何在雅虎中不启用“不太安全的应用程序”访问的情况下使用PHPMailer发送邮件？

Question

我正在尝试制作一个PHP联系表单并将消息发送到多个地址。我从默认地址发送它，我自己的，这是一个Yahoo地址，它是SMTP服务器，带有PHPMailer。

我正在使用带有PHP 5.6的主机。我在示例脚本中使用了最多的更新设置：

session_start();
date_default_timezone_set('Etc/UTC');
require_once('../phpmailer/PHPMailerAutoload.php');

echo '<pre>';
$mail = new PHPMailer;
$mail->CharSet = 'UTF-8';
$mail->SMTPDebug = 3;
$mail->isSMTP();
$mail->Host = 'smtp.mail.yahoo.com';
$mail->SMTPSecure = 'tls';
$mail->Port = 587;
$mail->SMTPAuth = true;
$mail->Username = '[e-mail]';
$mail->Password = 'my_password';

$mail->setFrom('[e-mail]', 'From Íñtërnâtiônàl form');
$mail->addAddress('[e-mail]', 'ラーメン丸 (ramen-maru)');
$mail->isHTML(true);    
$mail->Subject = '山本's demo mail (yamamoto)';
$mail->Body    = 'Delicious HTML message with extra umami <em>うま味</em>';
$mail->AltBody = 'Savoury plain text note with extra umami うま味, too.';

if(!$mail->send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent';
}
echo '</pre>';
die("ok\n");

它会输出以下内容：

2017-01-06 21:25:35 Connection: opening to smtp.mail.yahoo.com:587, timeout=300, options=array (
)

显然，尽管使用正确的用户名和密码进行了良好的身份验证，但它还是会因身份验证错误而失败。

如果我在Yahoo帐户安全中启用了“不太安全的应用程序”，那么它确实可以正常工作，如下所示：

那么，在不启用“不太安全的应用程序”的情况下，我需要做些什么来发送邮件？

在Gmail中，有很多教程可以使用OAuth2和创建应用程序密钥。它对Yahoo的工作方式是否相同？如果是这样，我需要做些什么才能使用PHPMailerOAuth？我在哪里申请密钥？它是哪一个密钥；Flberry、YQL、双子座？

Answer 1

在PHPMailer 5.2中，仅支持gmail。在PHPMailer 6.0中，支持许多其他版本。6.0尚未发布，但很快就会发布，请尝试一下。
