This is probably not your problem, but if you are to evaluate
arbitrary strings coming from an email, I would set up two security
measures: one is to ensure that only authorized emails run the code
and the other one to set up a safe environment for _reading_ the lisp
objects from the string. Ideally you would set up a package where
there is no access to system symbols and maybe some functions have
been removed. You might even want to deactivate #.  the reader macro
for executing code.
