So that the recipient can reply to the message. It has to put *something*
from the X.400 sender address in the RFC822 From line.

I mean I'll get mail from "Joe.Blow@foo.bar.something.something" and when I
reply to it I get a bounce from the X.400 gatweway telling me there are half
a dozen Joe Blows at foo.bar.

An X.400 address is more like a pattern. It specifies search criteria in
greater and greater detail, but there seems to be no fixed subset of an
address that uniquely specifies a recipient.

> 4) What are you doing with an address of the sender field in a reply?

I'm putting it in my "To" field.
