I posted this on your stack exchange question:

#+latex_class: report
#+options: author:nil  email:nil
#+latex_header: \author{Some user \thanks{\href{mailto:bla@comp.org}{bla@comp.org}}}

That is basically what ox-latex expands those keywords into.

Dear orgers,

I'd like to have a clickable mailto link in a latex pdf export (of a
report) for the #+email:-keyword's content.

I assume this is not achievable with latex commands, for example

   #+email: \href{mailto:a@b.com}{a@b.com}

because org escapes here backslashes and the braces:

  $\backslash$href\{mailto:a@b.com\}\{a@b.com\}

Is it possible to suppress this escaping or what mechanism to achieve a
clickable mailto link would you suggest?

Thank you very much

        Dieter
