[Exim] Splitting attachments

I am new to Exim having only just compiled and tested out the new
version (3.10)

We normally run Sendmail on Solaris but I would like to be able to see
if I can use Exim to do the following.

I would like to split and save in a directory the attachments on ALL
mail going to a particular account.

The attachments are always either .ZIP or .EXE files and I would like
to save just those, discarding the headers etc.

Is there a simple way to do this with Exim and if there is could
anyone tell me how?

Thanks in advance

Arvind
