well, that's what your configuration asks for, isn't it? any non-zero
exit code is a temporary error which means Exim will retry delivery
later. if your script sends the e-mail even it returns a non-zero code,
you'll need to change temp_errors to be more specific, or just remove
the line.

oh, now I get it, I think. but why are you using command
= /usr/sbin/exim? you can use transport_filter with the smtp driver,
too. at least it will be easier to debug it if you simplify it that
way.
