[Exim] About local_scan() -function

Hello,

Spec.txt of Exim 4 says it's not recommended to modify the file behind fd
which local_scan function get's as its argument.

So, how do I make updates in that file right way? Of course I can generate
a new message and try mail it, but what do I do with the old one?

    Regards,
        Petri
