I had some trouble with this not too long ago. I don't know what kind
of authentication your mail server requires, but to send through gmail
I had to do the following.

s = smtplib.SMTP('smtp.gmail.com')
s.set_debuglevel(1)
s.ehlo()
s.starttls()
s.ehlo()
s.login('foo', 'bar')
s.sendmail(from_address, to_addresses, msg)
s.close()

Hope that helps.
