Note well: this is using *envelope* sender, not the From: header. If
you don't understand the difference between these two, that's the first
thing you want to learn and master, because otherwise you're going to
find yourself in a large, confusing mess when trying to change behaviour
based on "sender".

You probably also want to look at the uses of headers related to From:,
such as Sender:.
