Rewriting "From" address

["Stan Brown" <stanb@awod.com>]

I am setting up a "stab;e" machine using the default postfix mail transport agent.
This machine lives on my home network, and I am able to send messages to outsidde
sitese from it, but I need to set it up to rewrite the "From" header to reflect my
adress at my ISP, so that mail will be delivered there (from which I will retrieve
it using fetchmail).

How can I do this?
