That was my understanding too.  I was under the impression that it is up to the 
receiving server to massage the headers so that it looked like the BCC recipient was 
the only one receiving the message.  But, when Ed Crowley said "BCC results in a 
separate message sent to each non-Exchange recipient", my confidence was broken and I 
bowed to the master.

So, masters and apprentices, which is it?  <Sacrilege> Is there any chance that 
<Genuflecting> The Great Ed Crowley </Genuflecting>* could be wrong?</Sacrilege>*

Actually, this appears to not be true.

Watching the mail come from our 5.5 IMS to our sendmail relay, only one 
message comes out, with two different envelope recipients, same as normal, 
even when both recipients are specified as BCC: recipients.

In my understanding, BCC: in SMTP is done by having the envelope recipients 
(required for mail routing) not appear in the *header* (visible by the 
end-user).

A mail admin along the route may still see the envelope recipients broken 
down into chunks (usually by domain) as usual.

Hope that helps,

Joel Noble
