Interesting.  The following has three LaTeX equations, one without any org LaTeX directives, one for inline use and one for LaTeX blocks.  Only the first works.

(please accept my apologies for sending an HTML formatted email to this list ;-)

* test

This is a test of the equations:

\begin{equation}
y = \sqrt{x}
\end{equation}

Alternatively, using LaTeX directives: first, the single line ~#+latex~ directive for an equation inline, say,
#+LATEX: y = f(x)
followed by a begin/end latex block:

* summary

The last one has disappeared completely.  The second is there in the raw email but has not been translated.  Only the first case works.  The export engine must work differently when exporting as a string?  It is indeed surprising that the whole begin/end latex block is removed from the raw text version, as you indicated in your OP.

This behaviour does seem rather strange.  Looking at org-mime.el, it is not obvious (to me) what is wrong.
