No, its a router pre-condition. It tests for an empty sender. (Well,
actually, it's also an ACL condition.) Just do something like
name:
driver = xxxx
senders = :
....
and that router will run only if the sender is empty, i.e. you have a
bounce message.

No. It is just syntactic sugar for
$sender_address is ""

A pipe does not run in a system filter. A pipe that is set up by a
system filter runs later in a pipe transport. Whether a bounce is
produced or not is controlled by the relevant options of the transport.
