[exim] Saving attachments

Hi,

I've been searching google and this list's archives for info on saving
attachments from incoming mail. I've managed to find some info regarding
using pipes etc, but I was hoping that there would be some way to tell
exim to save an attachment to disk?

Based on a recent thread Lena answered about unzipping attachments and
denying them if certain file types are found inside, I'd like to be able
to save the attachment so that I can manually see if it was a threat, or
if I need to ease up on what I'm blocking.

Thanks,

John..
