使用php从Unix weberver网站使用GMail SMTP服务器发送电子邮件

Question

我正在尝试使用以下php代码发送SMTP电子邮件。

    <?php

require_once "Mail.php";


$from = "info@XXXXX.com";
$to = "info@XXXXXX.com";
$subject = "Hi";
$body = "Hi,\n\nHow are you?\nDoing anything this Friday evening?\n";

 $host = "ssl://smtp.gmail.com";
 $port = "465";
$username = "xxxxx";
$password = "xxxxx";

$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>" );
}

 ?>

当我从Unix Web服务器网页执行代码时。 我收到以下错误。

authentication failure [SMTP: Invalid response code received from server (code: 535, response: Incorrect authentication data)]

但是上面的代码在我的本地主机工作正常。

请帮助我完成项目。

谢谢。

我遇到了同样的问题，您应该在G-Suite中启用SMTP，更多详细信息请参见： https ： //support.google.com/a/answer/2956491？hl = zh_CN
