I've taken a look at this and it looks kind of interesting but it appears to
need to run as the 'local delivery agent'. As the server on which the
quarantine system must run is just a mail gateway (no local users) it's not
something that can be used 'as is'. However, the guts of the macro detection
code appearr to be written in perl so I might be able to hash something
together from that!
Thanks,
Ian

I wonder if that will be of some help? It appears to be a (fairly complete)
framework for some fairly heavy munging of attachments....
I have not used it and cannot vouch for it's effectiveness :op
