So you say the Reply-To: field is to be ignored although in all other 
contexts it is preferred over the From: field. Say what you want, I don't 
understand that.

Quotes from RFC 5322:
"
    The "From:" field specifies the author(s) of the message,
    that is, the mailbox(es) of the person(s) or system(s) responsible
    for the writing of the message.
[...]
    The originator fields also provide the information required when
    replying to a message.  When the "Reply-To:" field is present, it
    indicates the address(es) to which the author of the message suggests
    that replies be sent.  In the absence of the "Reply-To:" field,
    replies SHOULD by default be sent to the mailbox(es) specified in the
    "From:" field unless otherwise specified by the person composing the
    reply.

    In all cases, the "From:" field *SHOULD NOT* contain any mailbox that
    does not belong to the author(s) of the message.  See also section
    3.6.3 for more information on forming the destination addresses for a
    reply.
"

And cctalk at ... is neither responsible for the writing of the message nor 
does it belong to the author of the message. But replies should be 
directed there, so there should be a Reply-To: field containing cctalk at ... 
and the From: field should contain the author's address.

EOD from my part ;-)
