For WSL

Add to ~/.muttrc the lines

macro pager  E        "<pipe-message>iconv -c --to-code=UTF8 > ~/.cache/mutt/mail.eml<enter><shell-escape>~/bin/wsl-open.sh $HOME/.cache/mutt/mail.eml<enter>"
macro attach B        "<pipe-entry>iconv -c --to-code=UTF8 > ~/.cache/mutt/mail.html<enter><shell-escape>~/bin/wsl-open.sh $HOME/.cache/mutt/mail.html<enter>"

and save under the path ~/bin/wsl-open.sh this shell script

#!/bin/sh
