Open attachment that contains forwarded email (MIME type message/rfc822)

When I forward an email with Mutt from my laptop, Mutt adds the forwarded email as an attachment with MIME type "message/rfc822".

Unfortunately, Android's stock email client "com.android.email" version 8.1.0 displays the received email like this:

Two things are wrong with that:

• It doesn't show the forwarded email's content.


• It doesn't show the content of the non-forwarded email, the body of the email I wrote in Mutt.

The email displays properly when using K-9 Mail.

Is there a way to make the email app show the email and its attachment?

I'm on a Samsung Galaxy J5 running LineageOS.
