This recommendation is because I think it is an unwise thing to do, and
I haven't worked out all the consequences.
For example, if you change the number of lines in the file, values that
Exim has computed (e.g. $body_linecount) may be wrong.
What kind of changes do you want to make?

If you return a failure code, the sender will get a bounce message.
However, if you just remove all the recipients and return an OK code,
the message is blackholed.
I am glad that somebody is experimenting with local_scan(). It was
invented at user request, but it does need some people to try it out, in
order to see what it limitations are and how it works in practice.
