I think version is. Knowing the name of a filter does no good if it's a
piece of software whose design has been completely overhauled 3 times in the
past year.

I think he means the address that the server is currently acting to deliver
to. In other words, a 'Filtering-On-Behalf-Of' header (obviously, it needs a
better name; 'Filtering-for-Delivery-to').

On the contrary, what about the situation where the mail admin doesn't care
about the user, and is thus causing a nuisance to the user. If the user can
use local client filters to counteract the actions taken based on a
particular label or filtering criterion, then having this avilable is very
important.
