Brain Fade. You can change it for e-mail and send, but Reply will not work,
so SPAM AWAY.

That would actually depend upon the email address used. A fake address
would obviously not work for a reply, but using a free web account in place
of your ISP email account would work.

There is no ' email address, though it takes a 'pacbell.net'
account log in to reach the server. Reply will go to an ' email
address; 'excite.com' has nothing to do with 'pacbell.net' Internet
connections, or 'prodigy.net' SMTP servers.

Here are the headers from a reply to the message of Exhibit A. There are no
AT&T Yahoo! HSI domain names in this message at all; not 'pacbell.net', not
'prodigy.net', not in any of the email addresses. Yet the forwarded message
did originate from an AT&T Yahoo! HSI account (and was, actually, forwarded
through an AT&T dial-up leased POP with Level 3).

There is nothing nefarious about doing this. There are good reasons to do
this. The convenience of using the mail client, in conjunction with the ISP
mail servers, without exposing the ISP email address to a party who doesn't
need it. In this day and age of merchants selling email addresses, this is
a rational step in protecting a private email address from spammers.
