MHT-File ist not shown in InternetExplorer
===

I have a mht-File which will not be shown in InternetExplorer 9. I have seen, that the text/html-part is encoded in base64:

    Content-Type: text/html; charset="utf-8"
    Content-Transfer-Encoding: base64

Could this be the reason, that IE9 will not be able to show the MHT-File?
