The reason $local_part is unset while running the system filter is that
the system filter is run once per message, at the start of delivery. A
message may have many recipients, so consequently there is no single
value that can be set in $local_part.
I suppose I should think about providing a variable containing a list of
all the recipients for use in the system filter. Not for user's filters,
of course. One thing you can currently do is to set log_recipients on,
and fish the data out of the log files.
