Amazon SES 自定义标头列表取消订阅不起作用

Question

我正在尝试在我发送的电子邮件中添加“列表取消订阅”标题（通过亚马逊 ses），但是当我看到收到的电子邮件时，其中没有这样的标题。我需要它来减少垃圾邮件投诉的数量并提高送达率和声誉。

SendEmailRequest sendEmailRequest = new SendEmailRequest();
sendEmailRequest.putCustomRequestHeader(UNSUBSCRIBE_HEADER, unsuscribeURL);

PS：使用其他提供商，例如 Mandrill 或 Sendgrid，它可以工作，但我在亚马逊确实需要它

所以...我找到了解决方法。 如果您想为消息添加自定义标头，请始终使用 RawMessage，而不是简单的。

类似这样的：

    SendRawEmailRequest sendRawEmailRequest = new SendRawEmailRequest();
    RawMessage rawMessage = null;
    rawMessage = buildSimpleRawMessage(...);
    sendRawEmailRequest.setRawMessage(rawMessage);


private RawMessage buildSimpleRawMessage(String subject, String message, Attachment attachment) {
    RawMessage rawMessage = null;
    try {
        // JavaMail representation of the message
        Session s = Session.getInstance(new Properties(), null);
        MimeMessage mimeMessage = new MimeMessage(s);

        // Subject
        mimeMessage.setSubject(subject);

        // Add a MIME part to the message
        MimeMultipart mimeBodyPart = new MimeMultipart();
        BodyPart part = new MimeBodyPart();
        part.setContent(message, "text/html");
        mimeBodyPart.addBodyPart(part);

        // Add a attachement to the message
        if(attachment!=null){
            part = new MimeBodyPart();
            DataSource source = null;
            source = new ByteArrayDataSource(attachment.getBuf(), attachment.getMimeType());
            part.setDataHandler(new DataHandler(source));
            part.setFileName(attachment.getFileName());
            mimeBodyPart.addBodyPart(part);
        }

        mimeMessage.setContent(mimeBodyPart);
        mimeMessage.addHeader(UNSUBSCRIBE_HEADER, unsubscribeURL);

        // Create Raw message
        ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
        mimeMessage.writeTo(outputStream);
        rawMessage = new RawMessage(ByteBuffer.wrap(outputStream.toByteArray()));
    } catch (Exception e) {
        logger.error("There was a problem creating mail attachment", e);
        throw Throwables.propagate(e);
    }
    return rawMessage;
}
