I would argue that this is way outside what the MTA (or at least exim)
should be doing....

Now having a hook so you can shove messages through some form of filter is
fine, and if you expand that filter to disinfect the file (make *very*
sure that you keep a backup copy - you'll need an untouched copy for your
legal case should it be deliberate) is OK. However lets try and keep
exim's role in this to a more generic level....

[Oh Malcolm, what have you unleashed :-) ]

Something I asked about a while back is the possibility to send a message
to a transport with all addresses intact from a filter (in particular the
system filter) - that would fit this use rather nicely. [not looked to
see if I can do it in the latest versions]. Its also a nice way of
handling spam mail - if your filters say its spam then pass it straight to
a BSMTP transport and file it on local disk. Then if your filters are
over imaginative you can just reinject it.
