Both of these reflect the envelope sender address used in the SMTP
dialog with the mail server.

You can restrict the set of headers used to identify subscribers using
the SENDER_HEADERS variable in mm_cfg.py, as Mark indicated. By default
(in Defaults.py) this is:
SENDER_HEADERS = ('from', None, 'reply-to', 'sender')
You can eliminate the envelope sender address from the mix by setting
this simply to:
SENDER_HEADERS = ('from', 'reply-to')
or drop 'reply-to' if you want to be even more restrictive.
