Note, this notion of "correctness" is not one of those pedantic types
of "correctness" that is "optional". Systems that forward mail to
all header recipients are severely broken, and will cause mail loops,
blacklisting by annoyed incorrect recipients, abuse by spammers, ...
So in short, forwarding systems must PRESERVE the original message
envelope and must not re-create fresh envelopes from message To/Cc
headers.
