MTAs don't "implement" Cc. MTAs (SMTP, see RFCs 821, 2821) have only
RCPT TO. The distinction between "To" and "Cc" is in (human) user space,
and is not well-defined even there. Moreover, while delivery
conventionally is consistent with user-level text in the message header,
there is no requirement that that be the case, just as with physical mail
(nothing prevents one from putting a check to a utility company in an
envelope addressed to a family member, or a personal letter intended for
a family member in an envelope addressed to a utility company). Don't
mess with user-to-user (message header) communications; see
