Hi. There.

I was trying to export  an email from gmail. and watching it inside
emacs.

gmail exports as eml. and there is a ruby utility eml2mbox, which I have
used for converting to mbox the eml file.

On emacs. I was trying to see which builtin mail client is simple for
opening mbox. For using less keystrokes rmail beat gnus. But rmail does
not render the email as gnus does. See the image below:

--8<---------------cut here---------------start------------->8---

--8<---------------cut here---------------end--------------->8---

Also. I have tried this with emacs -Q

--8<---------------cut here---------------start------------->8---
M-x gnus
G f
path
--8<---------------cut here---------------end--------------->8---

--8<---------------cut here---------------start------------->8---
C-u M-x rmail
path
--8<---------------cut here---------------end--------------->8---

ps:just in case. I am attaching the mbox file.
