I think it is useful to consider there as being three types of mail programs
instead of just two. There MTAs, MUAs and injection programs. I believe it
is the injection programs' responsibility to strip bcc headers. The issue
is a bit confused by sendmail, becuase the same binary runs in different
modes as both an MTA and an injection program.
