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:

Email app screenshot saying "Couldn't download. Touch to retry"

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.

    You're right, I had set mime_forward because I wanted to forward attachments per default. If I unset mime_forward, the forwarded email is just text (not a message/rfc822) and the stock email app shows it fine. Jun 19, 2020 at 19:27

Gmail cannot support this as I understand from FairEmail discussion on XDA (outlook mail client has related limitations).

There is a workaround, in case one is willing to have the forwarded email as text and not attachment.

OP had set mime_forward because they wanted to forward attachments per default . If this is unset as per mutt documentation (to ask-no or ask-yes), the forwarded email is just text (not a message/rfc822) and the stock email app shows it fine as confirmed by them.

  • The FairEmail discussion on XDA sounds interesting. Can you provide a link to it? Jun 21, 2020 at 12:08
  • You can search for "rfc822", even better would be reach out to developer--he is very prompt and helpful

  • It isn't a single instance I was quoting but the general sense of difficulties with various email clients, like this. My guess is FairEmail will support your need but it's best confirmed by you checking and if not asking developer to consider. I find him unbelievably supportive and tries his best to accommodate. I answered it just so that it may help somebody who comes looking for a solution, though this may not be what you want
