No one, except spam filters, read those. Also `X-message-flag` seems to be some Microsoft nonsense to begin with. And as much as I support the notion of text only emails, the reality is just different. Pretty much everybody sends out HTML mails. So just put this in your mailcap: text/html;w3m -dump %s;nametemplate=%s.html; copiousoutput and this in your .muttrc: auto_view text/html And voila! > This seems to be displayed by at least Microsoft MUAs, so that's > probably why it's being used. > > > I don't speak German, but this has a screenshot: > > https://www.msxfaq.de/exchange/clients/xmessageflag.htm > > -- > Nuno Silva > That content is ancient and in times of Office365 no longer relevant.
