使用 PHP 邮件程序发送带有附件的邮件时出错：事务失败：缺少起始边界 SMTP 代码：554

Question

我正在尝试发送带有 pdf 附件的 php mailer 电子邮件并显示此错误： 电子邮件未发送。错误：SMTP 错误：数据未接受。SMTP 服务器错误：DATA END 命令失败详细信息：事务失败：缺少开始边界 SMTP 代码：554

我尝试在所有地方添加哑剧边界，但结果相同。

<?php
include dirname(__FILE__) . '/../views/pdf-receipt.php';

function sendMailTest(
    $recipient_mail, $recipient_name, $from_mail, $from_name, $subject, $body, $body_without_html, $attachments=NULL
) {
    require 'folder/PHPMailer-5.2.26/PHPMailerAutoload.php';
    $mail = new PHPMailer;

    try {
        $mail->isSMTP();
        $mail->setFrom($from_mail, $from_name);
        $mail->addAddress($recipient_mail, $recipient_name);
        $mime_boundary = "Name of company".md5(time());
        $mail->SMTPDebug = true;
        $mail->Host = 'email-smtp.eu-west-1.amazonaws.com';
        $mail->Username = 'XXX';
        $mail->Password = 'XXX';

        $mail->Encoding = 'quoted-printable';
        $mail->addCustomHeader('Content-ID', '20cca', 'Content-Type', 'multipart/mixed', 'boundary='.$mime_boundary.'\n');
        $mail->Body = "--$mime_boundary\n";

        $mail->CharSet = 'UTF-8';
        $mail->Subject = utf8_encode($subject);

        $mail->Body .= "Hey\n";

        $mail->AltBody .= "--$mime_boundary\n".$body_without_html;

        $mail->SMTPAuth = true;

        $mail->SMTPSecure = 'tls';
        $mail->Port = 000;

        $mail->isHTML(true);
        $data = '%PDF-1.2 6 0 obj << /S /GoTo /D (chapter.1) >>';       
        // if i comment line below email is sent properly, 
        // if i use AddAttachment local pdf file its working also, 
        // but i use TCPD generated PDF and attaching it, if i will 
        // just write it out to the message body i will see it as a 
        // text or if i will attach 'addStringEmbeddedImage' its 
        //displayed correctly but on same line as message text

        // $attachments is pretty much this:
        // $pdf->Output("test.pdf", "S");
        // tried this $mail->Body .= "--$mime_boundary\n"; before next line
        // did not help
        $mail->AddStringAttachment($attachments, 'base64', 'application/pdf');

        if($mail->send()) {
            return;
        }
    } catch (Exception $e) {}

    echo 'E-mail not sent. Error: ', $mail->ErrorInfo, PHP_EOL;
}
?>

我希望发送带有附件的电子邮件，但没有看到起始边界错误。

首先，我真的希望您实际上并没有使用 PHP 5.2。

你在这里玩得很开心：

    $mail->addCustomHeader('Content-ID', '20cca', 'Content-Type', 'multipart/mixed', 'boundary='.$mime_boundary.'\n');
    $mail->Body = "--$mime_boundary\n";

你使用 PHPMailer 的原因是你不必做这样的事情；它已经为你处理好了。当你试图像这样颠覆它时，它只会弄得一团糟，正如你所发现的那样。

您已经努力将 PHPMailer 代码包装在 try/catch 块中，但您没有告诉 PHPMailer 抛出异常（通过将 true 传递给构造函数），并且您的 catch 块是空的，所以它什么也没做。

我已对其进行了重写以解决这些问题，并更合乎逻辑地分组设置：

include dirname(__FILE__) . '/../views/pdf-receipt.php';

function sendMailTest(
    $recipient_mail,
    $recipient_name,
    $from_mail,
    $from_name,
    $subject,
    $body,
    $body_without_html,
    $attachments = null
) {
    require_once 'folder/PHPMailer-5.2.26/PHPMailerAutoload.php';
    $mail = new PHPMailer(true);

    try {
        $mail->isSMTP();
        $mail->SMTPDebug = 2;
        $mail->Host = 'email-smtp.eu-west-1.amazonaws.com';
        $mail->SMTPSecure = 'tls';
        $mail->Port = 587;
        $mail->SMTPAuth = true;
        $mail->Username = 'XXX';
        $mail->Password = 'XXX';

        $mail->CharSet = 'UTF-8';
        $mail->setFrom($from_mail, $from_name);
        $mail->addAddress($recipient_mail, $recipient_name);
        $mail->Subject = $subject;

        $mail->Body .= $body;
        $mail->AltBody = $body_without_html;

        $mail->isHTML(false);
        $data = '%PDF-1.2 6 0 obj << /S /GoTo /D (chapter.1) >>';

        $mail->addStringAttachment($data, 'receipt.pdf');

        $mail->send();
    } catch (Exception $e) {
        echo 'E-mail not sent. Error: ', $mail->ErrorInfo, PHP_EOL;
    }
}
