Concentrating on the error itself: when it occurs, the variable $user_email hasn't been untainted. That's the only reason you'd get that error in reference to that line.
Perl checks more than taintedness of the argument to pipe open. It also checks whether a bunch of environment variables are either not set, or untainted. See man perlsec for details.
