How can I include a large block of regex with LaTeX?

Is it possible to include a large block of a regex (like this one: http://www.ex-parrot.com/pdw/Mail-RFC822-Address.html) without escaping all colliding characters first?

I think of something like

\begin{following_section_will_not_be_parsed_by_latex}
(a+?b)
\end{...}

You can include \usepackage{listings} and then use

\begin{lstlisting} [code|regex|whatever] \end{lstlisting}

Look at fancyvrb package. From the README:

The `fancyvrb' package provides very sophisticated facilities for reading and writing verbatim TeX code. Users can perform common tasks like changing font family and size, numbering lines, framing code examples, colouring text and conditionally processing text.

So you can do something like:

\documentclass{article}
\usepackage{fancyvrb}
\begin{document}
\begin{Verbatim}[fontsize=\small,frame=single,label=RFC822 regexp]
...
\end{Verbatim}

In order to not clutter your Latex file with the huge regex, you can include a file verbatim as well.

Use a verbatim block. But it won't look very nice :(
