You shouldn't listen to crickets. You don't say which release of Exim
you are using, but this is possible with both Exim 3 and Exim 4. Just
pipe the message to your script. If it wants to re-send it, get it to
pipe the message back to Exim. Or on to procmail for delivery.
This is no different from one way of scaning for spam, viruses, etc.
There are comments about it in the Exim 4 book and in the FAQ. And it's
been discussed on this list a lot.

In a user's .forward file, put
|/some/script email@???
However, Exim doesn't use a shell by default. If you want to pipe it on,
as you are doing, either interpose another script, or use
|/bin/sh -c 'whatever....'
All this stuff is to be found in the docs and FAQ.
