Delphi/Indy 10 - 发送带附件的文本或HTML邮件会为文本（正文）本身添加一个附件

emaildelphiattachmentindy10delphi-10.2-tokyo
8
多年来，我们一直使用Indy 10发送电子邮件（文本，而非HTML），并附加一个或多个PDF文件，我们从未遇到任何问题。最近（可能是自东京发布3以来？），我们的客户注意到电子邮件的文本部分（正文）现在是一个附件，而不是电子邮件本身的一部分。我在互联网上搜寻了解决方案，并尝试了所有测试，但没有解决这个问题。我尝试了Remy Lebeau在StackOverflow上提出的一些解决方案，但没有成功。

The body is an attachment

这是代码（基于在StackOverflow上找到的帖子）

procedure TForm1.btnSendEmailClick(Sender: TObject);

var
   smtp   : TIdSMTP;
   msg    : TidMessage;
   builder: TIdMessageBuilderHtml;

begin
   msg := TidMessage.Create(nil);

   try
      builder := TIdMessageBuilderHtml.Create();

      try
         // FIsBodyHtml IS FALSE
         if FIsBodyHtml then begin
            builder.Html.Text   := edText.Lines.Text;
            builder.HtmlCharSet := 'utf-8';
            builder.HtmlContentTransfer := 'quoted-printable';
         end else begin
            builder.PlainText.Text := edText.Lines.Text;;
            builder.PlainTextCharSet := 'utf-8';
            builder.PlainTextContentTransfer := 'quoted-printable';
         end;

         // Add attached file here
         if (edFile.Text <> '') and FileExists(edFile.Text) then begin
            builder.Attachments.Add(edFile.Text);
         end;

         builder.FillMessage(msg);
      finally
         builder.Free;
      end;

      msg.From.Name    := 'From name here';
      msg.From.Address := 'From email address here';
      msg.Subject      := edSubject.Text;

      msg.Recipients.EmailAddresses := edEMail.Text;
      // msg.CCList.EmailAddresses     := CCAddresses;
      // msg.BccList.EmailAddresses    := BCCAddresses;

      smtp := TIdSMTP.Create(nil);

      try
         smtp.Host     := 'Host IP here';
         // Smtp.UseTLS   := utNoTLSSupport;
         smtp.Port     := 25;
         // smtp.Username := '';
         // smtp.Password := '';
         // smtp.AuthType := satDefault;

         smtp.Connect();

         try
           smtp.Send(msg);
         finally
           smtp.Disconnect;
         end;

      finally
         smtp.Free();
      end;
   finally
     msg.Free();
   end;

   ShowMessage('EMail with attachment sent.');
end;

无法重现，并且代码看起来没有问题。请提供TIdMessage实际生成的原始邮件数据。我怀疑问题可能是接收方的问题（如有缺陷的读取器等）。 - Remy Lebeau
谢谢Remy抽出宝贵的时间回答我的问题。今天早上，我给自己发送了一封电子邮件，以展示原始电子邮件数据，但我不知道在夜间发生了什么事情，但是正文现在显示正确（未附加到消息）。看起来我们的服务提供商在晚上更改了一些东西（软件更新？）。许多客户都有相同的提供商。这可能有关吗？很可能。我将向您展示更改前后相同电子邮件的原始数据。 - Phanault

在您的第一个示例中，纯文本的“Content-Disposition”具有不属于它的“filename”属性。在您的第二个示例中，该属性缺失。 - Remy Lebeau

我投票关闭此问题，因为它无法再现。 - Remy Lebeau
我遇到了非常类似的问题。我正在研究上面的示例。我认为在indy博客上发布有关正确使用TIdMessageBuilderHtml的另一篇博客文章会很棒。看起来很难确定大多数电子邮件客户端可以生成和接受什么。 - Warren P

我们在使用微软邮件时遇到了同样的问题。这是由于文本部分中的“Content-Disposition: inline”行导致MS Mail将文本部分显示为可下载附件所致。删除Content-Disposition行可以解决此问题，但需要修改TIdMessageClient.SendBody。坦率地说，我认为这是MS Mail的问题。
