Comment (by raimue):

 For NeoVim, we could add this as a local patch if needed. I did not add
 any neovim-devel port, as I do not follow the upstream development too
 closely, so I would not know when it is worth to update such a port.

 However, in general the quickest workaround would be to just add the
 corresponding `autocmd` to your (Neo)Vim configuration files in
 `~/.vim/filetype.vim`:

 {{{
 au BufNewFile,BufRead neomutt-*-\w\+,neomutt[[:alnum:]_-]\\\{6\} setf mail
 }}}
