I try: 


\begin{equation}
\neg \neg A \vdash_{m} A
\end{equation}


It seems  that it will  work for the equation  package, but it  does not
work with  for example  other packages: the  prooftree command  given by
bussproofs package does not work,

\begin{prooftree}
\AxiomC{$A$}
\AxiomC{$A \to \bot$}
\RightLabel{\scriptsize{$\to E$}}
\BinaryInfC{$\bot$}
\end{prooftree}


neither fitch proofs: 

\begin{equation*}
\begin{fitch}
\fh A & H \\
\fa \fh \bot & H \\
\fa A \to \bot 
\end{fitch}
\end{equation*}

The scientific community  can live without this tool, of  course, but it
would be nice if Org + Gnus  could be the email client par excellence of
this community. I am happy to see that you agree. 

Best wishes,

[fn:1] I guess  that  by "inlining"  you mean  making  the command  M-x
org-mime-htmlize  . But  I am  not sur  that is  what you  meant. It  is
nevertheless already  a great pleasure of  making Org working in  Gnus !
What a terrific tool !
