I'm writing a new email, and in that email I'm referring to a couple of other emails and I want to include them as attachments. When I drag and drop a mail to the mail I'm writing, some icon appears but when I double click on it, it shows plain text with headers, and not a nice formatted mail.
How can I attach it properly?
ATTENTION!! I know about "Mail -> Message -> Forward as Attachment" but it is not working properly: when I double-click on attached icon, it opens as text (with headers) and not as nice formatted mail. I also know about "Save as RTF" - but this is also not a proper solution as headers are lost.
For example, when I attach email in Thunderbird or Outlook, it attaches EML file - and when I open it, it is displayed properly (with formatting), and it is also has all headers (but not visible by default).
