Can a person successfully subscribe to a listserv list when their From: and
Sender: line are slightly different?  If so, which flavor shows up in the
list?
For example, what if my headers looked like:
        From: [log in to unmask]
        Sender: [log in to unmask]
What would happen?  I suspect that once I got subscribed it wouldn't matter
since listserv seems to be more forgiving about headers in mail to lists as
opposed to mail to the server itself containing commands.
