With

    .sendmail(self, from_addr, to_addrs, msg, mail_options=[], rcpt_options=[])

email will be sent to all people in to_addrs. The headers you put into msg
don't matter for delivery at all.

What you could do is write a wrapper for .sendmail that evaluates the
To/CC/BCC headers in a message text and constructs the appropriate list for
to_addrs.
