Well I'm getting it now, thank you.
The post service doesn't care what Cc: you write on your letters either, but only looks at the envelope.
Yes, I assumed an MTA may do some extra processing based on the headers added after DATA.
Yes to the RCPT TO (and do mind the syntax, you'd got it wrong) -- and Postfix is not supposed to tamper witht the Bcc:, in fact, cleanup(8) is not consistently documented to eliminate Bcc: headers.
Right, I understand.
There are several ways - the safest and easiest is not to include the Bcc header at all (it is a crutch for setups that do not specify an envelope, as, for instance, sendmail -t -i or sendmail -t -oi), and just specifying the recipients-to-be-bcc'd in RCPT TO:<> commands. You don't need such a crutch if you're talking SMTP.
Using multiple RCPT TO:<> commands make the most sense yes. I just never really used Bcc (not in the habit of blindly copying many recipients) this way and thought it to be a clutch added by the MUA that may or may not work depending on the MTA. So I tested it with postfix to see its behaviour.
I wasn't aware that I could use multiple RCPT TO:<> commands to accomplish Bcc. Hence me adding Bcc after the DATA.
