自從上傳網站後PHPMailer無法正常工作

Question

由於我已經將我的網站上傳到服務器，因此我無法使用PHPMailer發送smtp郵件。它在我的本地服務器（XAMPP）上工作過。我使用GMAIL，因此我還更改了所有必需的gmail設置（即，我創建了另一個OAuth2令牌）。然而，它只是將無法正常工作......

我使用（而這也是脫機工作）的PHP代碼如下：

<?php 
/** 
* This example shows settings to use when sending via Google's Gmail servers. 
*/ 

//SMTP needs accurate times, and the PHP time zone MUST be set 
//This should be done in your php.ini, but this is how to do it if you don't have access to that 
date_default_timezone_set('Etc/UTC'); 

//Load dependencies from composer 
//If this causes an error, run 'composer install' 
require 'vendor/phpmailer/phpmailer/PHPMailerAutoload.php'; 

//Load dependencies from composer 
//If this causes an error, run 'composer install' 
require 'vendor/autoload.php'; 

//Create a new PHPMailer instance 
$mail = new PHPMailerOAuth; 

//Tell PHPMailer to use SMTP 
$mail->isSMTP(); 

//Enable SMTP debugging 
// 0 = off (for production use) 
// 1 = client messages 
// 2 = client and server messages 
$mail->SMTPDebug = 0; 

//Ask for HTML-friendly debug output 
$mail->Debugoutput = 'html'; 

//Set the hostname of the mail server 
$mail->Host = 'smtp.gmail.com'; 

//Set the SMTP port number - 587 for authenticated TLS, a.k.a. RFC4409 SMTP submission 
$mail->Port = 587; 

//Set the encryption system to use - ssl (deprecated) or tls 
$mail->SMTPSecure = 'tls'; 

//Whether to use SMTP authentication 
$mail->SMTPAuth = true; 

//Set AuthType 
$mail->AuthType = 'XOAUTH2'; 

//User Email to use for SMTP authentication - Use the same Email used in Google Developer Console 
$mail->oauthUserEmail = "mygmail@gmail.com"; 

//Obtained From Google Developer Console 
$mail->oauthClientId = "IWONTTELLU.apps.googleusercontent.com"; 

//Obtained From Google Developer Console 
$mail->oauthClientSecret = "IWONTTELLU"; 

//Obtained By running get_oauth_token.php after setting up APP in Google Developer Console. 
//Set Redirect URI in Developer Console as [https/http]://<yourdomain>/<folder>/get_oauth_token.php 
// eg: http://localhost/phpmail/get_oauth_token.php 
$mail->oauthRefreshToken = "1/IWONTTELLU"; 

//Set who the message is to be sent from 
//For gmail, this generally needs to be the same as the user you logged in as 
$mail->setFrom('mygmail@gmail.com', 'BLA'); 

//Set who the message is to be sent to 
$mail->addAddress('my@privatemail.com', 'Hi'); 

//Set the subject line 
$mail->Subject = 'PHPMailer GMail SMTP test'; 

//Read an HTML message body from an external file, convert referenced images to embedded, 
//convert HTML into a basic plain-text alternative body 
$mail->msgHTML(file_get_contents('contents.html'), dirname(__FILE__)); 

//Replace the plain text body with one created manually 
$mail->AltBody = 'This is a plain-text message body'; 

//Attach an image file 
$mail->addAttachment('images/phpmailer_mini.png'); 

//send the message, check for errors 
if (!$mail->send()) { 
    echo "Mailer Error: " . $mail->ErrorInfo; 
} else { 
    echo "Message sent!"; 
} 

?> 

當我嘗試，它首先用它上網的所有需要​​很長的時間，直到我得到一個錯誤（也嘗試使用gethostbyname('smtp.gmail.com');長話短說：也沒有工作，其次），我得到的代碼是Error: Failed to connect to server: Connection timed out (110) & SMTP connect() failed。我使用的服務由1and1提供（1und1/1 & 1）。我一直試圖解決這個問題超過4個小時，並且無法找出問題所在。不太安全的應用程序可以訪問，我也創建了一個令牌並「創建」了一個刷新令牌，如https://github.com/PHPMailer/PHPMailer/wiki/Using-Gmail-with-XOAUTH2。故障排除指南（https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting）也無法真正幫助我，儘管我認爲它在驗證過程中遇到了問題......我也嘗試使用ssl（當然，我也更改了端口等），但它們都不起作用。

端口587是否仍受gmail支持？你可能想要你的SSL端口465.這篇文章可能也是有用的https://www.wpsitecare.com/gmail-smtp-settings/或可能是1 & 1被gmail阻止？看到這篇文章http://docs.mailpoet.com/article/61-sending-with-gmail-doesnt-work
