With the simple filter example the virtual aliases expansion is
both before and after the filter.
> Where is this documented?
virtual alias expansion is done in the cleanup daemon (described in
ADDRESS_REWRITING_README.html).
It is configurable with receive_override_options which is documented
under Advanced content filter :-(
I suppose that the simple filter is meant to be simple, if you want
sophistication, the smtp-based approach is better.
