i have passed on your email to the appropriate parties...  one.digital.cnet.com is misleading as it is not hosted directly by cnet.com.  newsletter-support@cnet.com is incorrect.  this is actually an affiliation between zdnet.com and flonetwork.com (zdnet.com is part of the cnet networks family).

apologies

Are you saying that <CNET_Digital_Dispatch@one.digital.cnet.com>
is not a valid e-mail address?  If so, why can I send mail to it?

No SMTP error, and I have never received a bounced message for
that address.  It sure looks valid to me...  And if it still
isn't valid, then how come it sends mail to us?  You don't say
that you use fake sender addresses on your outbound e-mail, do
you?  Here is a header excerpt from a timestamped message:

Return-Path: <CNET_Digital_Dispatch@one.digital.cnet.com>
Received: from uuout11smtp6.uu.flonetwork.com ([205.150.6.46]:2159 "EHLO
        uuout11smtp6.uu.flonetwork.com") by emberiza.its.uu.se with ESMTP
        id <S12417AbRGFCB6>; Fri, 6 Jul 2001 04:01:58 +0200

The Return-Path line indicates the SMTP envelope sender address,
as specified in MAIL FROM.  It must be a valid mailbox, or we
won't be able to return an error message to the sender if there
is a delivery problem.  It must not be a null sink that throws
away everything sent to it.
