使用带有 Gmail 帐户的 PHPMailer 发送邮件

Question

我正在尝试使用 PHPMailer 库从我的网站发送电子邮件。我这样做的目的是：

1. 我从这个链接下载了 PHPMailer 5.2-stable 。

2. 我在我的主机上上传了以下文件：class.phpmailer.php、class.smtp.php和PHPMailerAutoload.php

3. 然后我创建了一个文件名 contact.php 并在其中编写了以下代码：

   require 'phpmailer/PHPMailerAutoload.php';
   $mail = new PHPMailer();
   $mail->SMTPDebug = 1;  
   
   $mail->SMTPAuth = true; 
   $mail->IsSMTP();
   $mail->Host = "smtp.gmail.com";
   $mail->Username = "*****************"; //My Email Address
   $mail->Password = "*****************"; //My Email's Address
   $mail->SMTPSecure = "tls";   
   $mail->Port = 578; 
   
   $mail->AddAddress('*****************');
   $mail->From = "*****************";
   $mail->FromName = "Website Contact Form - " . "Website Name";
   $mail->Subject = "New Message from Contact Form";
   
   $mail->Body    = 'This is the HTML message body <b>in bold!</b>';    
   $mail->AltBody = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test
   $mail ->isHTML(true);
   $message = NULL;
   if(!$mail->Send()) {
      $message = "Mailer Error: " . $mail->ErrorInfo;
   }else{
      $message = "Message sent!";
   }
   

但是在运行此文件后，我收到以下错误：

2021-06-25 11:44:54 SMTP 错误：无法连接到服务器：网络无法访问 (101) SMTP connect() 失败。

我尝试了几封电子邮件，包括直接从我的托管服务发送的电子邮件地址、Gmail 帐户和 Google Workspace 电子邮件（以前称为 Gsuit）。所有失败的产生提到的错误。

最后，我认为值得一提的是，我的托管服务不支持 PHP 的 mail() 功能，这就是我需要使用 SMTP 的原因。

更新：联系主机并尝试了很多后，虽然我确定输入了正确的用户名和密码，但出现以下错误：

Answer 1

1. 确保您的帐户启用了“不太安全的应用程序访问”设置。 https://support.google.com/accounts/answer/6010255?hl=en#zippy=%2Cif-less-secure-app-access-is-on-for-your-account

2. 其次，确保您的主机允许使用传出端口 578，或者您甚至可以请求他们启用传出端口。

3. 尝试使用ssl代替tls，这样更安全可靠。
