Note, adding Cc: recipients is tricky, because while most implementations
support multiple "Cc:" headers, the RFC clearly specifies that a message
must have exactly one "Cc:" header containing all the Cc: recipients.
Automated tools that modify the "Cc:" list must append elements to the
Cc: header. So "PREPEND" is not a portable option.

If my response solves your problem, the best way to thank me is to not
send an "it worked, thanks" follow-up. If you must respond, please put
"It worked, thanks" in the "Subject" so I can delete these quickly.
