I know this isn't what you want to hear, but this would probably be much
easier to implement in Exim 4. In Exim 4 you can have ACLs (access control
lists) that test the data portion of a message. With the Exiscan patch, you
can also write ACLs that test individual MIME segments. This gives you a
really powerful and flexible way to do content filtering.

In Exim3, your best bet may be to write an external script to do your tests,
then use the transport_filter feature to call it.
