I presume you mean -bS rather than -bs.

Early versions of Exim tried to carry on with -bS when there was a
problem, but it got very complicated. After some discussion (a couple of
years ago now, I can't remember exactly when) we reached the conclusion
that the best thing to do was to abort the entire batch and let a human
sort it out. The problem is that there is no convenient way of handling
multiple errors.
Essentially, -bS expects the input to have been previously validated.

What would you do with an illegal sender?
Either you must pre-validate the input, or you'll need to write a
program to read the BSMTP and feed it to Exim interactively, using -bs.
Then you can catch each error as it happens, and do whatever you want.
