You do understand that the B in BCC means BLIND, right? It wouldn't be 
very blind if the BCC information were included in the message data.


The purpose of BCC is to send a copy to the BCC recipients without there 
by anything in the message data (note that message headers are part of the 
message data as far as SMTP is concerned) to indicate that a copy was sent 
to the BCC recipients. To do otherwise would fundamentally break the 
definition of BCC.


(perhaps part of the problem is younger folk, rarely if ever exposed to 
traditional office paper communications, are not familiar with why the 
term is "carbon copy", when "blind carbon copies" were used, and perhaps 
have never even seen carbon paper)

no because BCC is never in the headers
this would break BCC per definition what BCC is

I read the thread but I don't understand if it's possible to have Bcc
parameter in the header of the message.
Here is an extract of the message sent (wireshark tcp stream):

And as you can see the Bcc is missing...
