What Exim calls a "system filter" is applied to *all* deliveries, both
inbound and outbound. However, it is run only once per message, not once
per address.

Surely the easiest way to do this is just to extract the entries from
your domain from the log? Check out the "exigrep" utility.

That will run the filter file for all incoming mail, for each local
address.

It wouldn't. Once the pipe has been encountered, there is no more
directing to be done.

You will need to put a user= option on the "address_pipe" transport so
that Exim knows who to run it as, since you are generating a pipe
address from a place that doesn't have an associated user. However, as I
said above, this will run only once per message, and it sounds as if
that isn't what you are after.
