PHP邮件未到达Amazon EC2上的目的地[重复]

PHP mail function doesn't complete sending of e-mail （26个答案）

[<6天前关闭。

我正在尝试使用PHP的mail()函数从Amazon EC2上的服务器发送电子邮件。该函数返回true，但电子邮件未到达目的地。我对该主题进行了研究，并尝试设置sendmail和sendmail-cf，但没有解决问题。这是代码：

$EmailTo = ...; //destination email
$Subject = "New Message Received.";
$Body = "";
$Body .= "Name: ";
$Body .= $name;
$Body .= "\n";
$Body .= "Email: ";
$Body .= $email;
$Body .= "\n";
$Body .= "Subject: ";
$Body .= $msg_subject;
$Body .= "\n";
$Body .= "Message: ";
$Body .= $message;
$Body .= "\n";

try{
     $success = mail($EmailTo, $Subject, $Body, "From:".$email);
     echo $success;
}catch(Exception $e){
     echo "Something went wrong. Please try again.";
}

所有变量均从表单的$_POST请求中获取并经过验证。 
任何提示都值得赞赏。

代替使用php mail（）函数，您可以使用PHPMailer类，这可能是最好的选择，因为它也可以在没有本地邮件服务器的情况下运行（集成SMTP支持）。

您可以通过composer require phpmailer/phpmailer安装它，或从https://github.com/PHPMailer/PHPMailer这里下载它。您可以在同一链接上了解更多信息。

例如，这是一个简单的脚本。

require 'vendor\autoload.php'; // For composer

require 'path/to/PHPMailer/src/Exception.php';  // If you are 
require 'path/to/PHPMailer/src/PHPMailer.php';  // downloading it without
require 'path/to/PHPMailer/src/SMTP.php';       // composer then include these.

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
use PHPMailer\PHPMailer\SMTP;

try 
{
    //Server settings
    $mail->SMTPDebug = SMTP::DEBUG_SERVER;                      // Enable verbose debug output
    $mail->isSMTP();                                            // Send using SMTP
    $mail->Host       = 'smtp1.example.com';                    // Set the SMTP server to send through
    $mail->SMTPAuth   = true;                                   // Enable SMTP authentication
    $mail->Username   = '[email protected]';                     // SMTP username
    $mail->Password   = 'secret';                               // SMTP password
    $mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;         // Enable TLS encryption; `PHPMailer::ENCRYPTION_SMTPS` encouraged
    $mail->Port       = 587;                                    // TCP port to connect to, use 465 for `PHPMailer::ENCRYPTION_SMTPS` above

    //Recipients
    $mail->setFrom('[email protected]', 'Mailer');
    $mail->addAddress('[email protected]', 'Joe User');     // Add a recipient
    $mail->addAddress('[email protected]');               // Name is optional
    $mail->addReplyTo('[email protected]', 'Information');
    $mail->addCC('[email protected]');
    $mail->addBCC('[email protected]');

    // Attachments
    $mail->addAttachment('/var/tmp/file.tar.gz');         // Add attachments
    $mail->addAttachment('/tmp/image.jpg', 'new.jpg');    // Optional name

    // Content
    $mail->isHTML(true);                                  // Set email format to HTML
    $mail->Subject = 'Here is the subject';
    $mail->Body    = 'This is the HTML message body <b>in bold!</b>';
    $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

    $mail->send();
    echo 'Message has been sent';
} 
catch (Exception $e) 
{
    echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}
