in the message itself.

from_addr and to_addrs are commands to the
mail transport; everything that you want to go
into the message header should be explicitly put
into the message.

(the mail transport agent may rewrite some of
the headers, but don't rely on that...)

here's an example from the eff-bot guide (see
footer for more info):

# File: smtplib-example-1.py

import smtplib
import string, sys

HOST = "localhost"
FROM = "effbot at spam.egg"
TO = "fredrik at spam.egg"

SUBJECT = "for your information!"

BODY = "next week: how to fling an otter"

body = string.join((
    "From: %s" % FROM,
    "To: %s" % TO,
    "Subject: %s" % SUBJECT,
    "",
    BODY), "\r\n")

print body

server = smtplib.SMTP(HOST)
server.sendmail(FROM, [TO], body)
server.quit()
