My wild guess is that the trouble is in `if "@" in mail` . You can only
test somthing `in` something if the second thing is iterable. So when
you don't supply a value via `?mail=' -- maybe the code that sets the
value of `mail` from the URL (code you don't show us) sets `mail=None`,
your server-side code blows up. Things would be simpler if you included
a traceback in your error logging.
