When you say "with a qmail 1.03 smtp server for outgoing mail," do you mean
that this message was injected with SMTP? If so, then qmail-inject never saw
the message. qmail-smtpd doesn't look at the headers, and execs qmail-queue to
queue the message as is. It's the responsibility of the software on the remote
end to strip the Bcc field and turn it into SMTP "RCPT TO" commands.
