Hello

Now that the bug in org-mime-htmlize is fixed, I would like
to comment on the visual representation. Most likely this
has to do with the mml package.

When I write the following message 
Integral


$$\int fdx=0$$
And


\begin{equation} 
\sum_{\alpha} 
\end{equation}

and apply org-preview-latex-fragment and then
org-mime-htmlize and send this message to gmail. 
The 'gmail-reader' displays them fine.

However thunderbird does not and I apply the resulting eml 
file below (I presume a screenshot is not appropriated)

Now tunderbird itself has an extension (latex-it) which does
something similar to org-mime-htmlize, it sends latex math
as png. However there are "better* displayed, I attach the
relevant eml file below.

Could org-mime-htmlize use the structure of latex-it?

Thanks
