PHPMailer和附件的100K文件限制？

Question

我正在尝试将文件作为电子邮件附件发送，但由于某种原因，如果文件大于 100k，则即使我收到电子邮件发送的消息，电子邮件也不会通过。
这也可能是对 IIS smtp 设置中附件的限制，但是当我取消选中限制会话大小和限制邮件大小选项时，它并没有改变任何东西。今晚可能要重启服务器了……

不知道是php.ini设置还是什么。

<?
$path_of_attached_file = "Images/marsbow_pacholka_big.jpg";

require 'include/PHPMailer_5.2.1/class.phpmailer.php';
try {
    $mail = new PHPMailer(true); //New instance, with exceptions enabled

    $body = $message; //"<p><b>Test</b> another test 3.</p>";

    $mail->AddReplyTo("admin@example.com","Admin");

    $mail->From     = "admin@example.com";
    $mail->FromName = "Admin";

    $mail->AddAddress($to);
    $mail->Subject  = "First PHPMailer Message";
    $mail->AltBody  = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test
    $mail->WordWrap = 80; // set word wrap

    $mail->MsgHTML($body);

    $mail->IsHTML(true); // send as HTML
    if($attach){
        $mail->AddAttachment($path_of_attached_file);
    }

    $mail->Send();
    echo 'Message has been sent.';
} catch (phpmailerException $e) {
    echo $e->errorMessage();
}
?>

我可能错了，因为我不使用 IIS，但您提供的代码实际上会使用本机 MTA 而不是 SMTP。据我所知，您必须使用 IsSMTP() 方法让 PHPMailer 知道您打算使用 SMTP。

类似这样的：

<?
$path_of_attached_file = "Images/marsbow_pacholka_big.jpg";

require 'include/PHPMailer_5.2.1/class.phpmailer.php';
try {
    $mail = new PHPMailer(true); //New instance, with exceptions enabled

    $body = $message; //"<p><b>Test</b> another test 3.</p>";
    $mail->IsSMTP(); // telling the class to use SMTP
    $mail->Host       = "mail.yourdomain.com"; // SMTP server
    $mail->SMTPDebug  = 2;
    $mail->SMTPAuth   = true;                  // enable SMTP authentication
    $mail->Host       = "mail.yourdomain.com"; // sets the SMTP server
    $mail->Port       = 25;                    // set the SMTP port 
    $mail->Username   = "yourname@yourdomain"; // SMTP account username
    $mail->Password   = "yourpassword";        // SMTP account password 

    $mail->AddReplyTo("admin@example.com","Admin");

    $mail->From     = "admin@example.com";
    $mail->FromName = "Admin";

    $mail->AddAddress($to);
    $mail->Subject  = "First PHPMailer Message";
    $mail->AltBody  = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test
    $mail->WordWrap = 80; // set word wrap

    $mail->MsgHTML($body);

    $mail->IsHTML(true); // send as HTML
    if($attach){
        $mail->AddAttachment($path_of_attached_file);
    }

    $mail->Send();
    echo 'Message has been sent.';
} catch (phpmailerException $e) {
    echo $e->errorMessage();
}
?>

您的代码实际上并未检查消息是否已发送。 您需要更改代码以检查发送方法的返回

if ($mail->Send())
  echo 'Message has been sent.';
else
  echo 'Sorry there was an error '.$mail->ErrorInfo;

这应该会给你一个错误消息，说明如果它确实出错了会发生什么。
