seems complicated. Lena's approach is better (using the ${address:…}
operator.

The rules from the rewrite section are applied at the time the
message is receveived (as written in the spec file). So, at the time
the envelope gets rewritten, the $h_from: isn't set yet.

Probably you need to rewrite at transport time. But … the envelope
sender can't be rewritten at transport time, transports have a
"return_path" option for modification of the envelope sender.

[The usual disclaimer: I may be wrong, I didn'nt cross check with the
documentation.]
