Thanks for the advice. I don't think I'm quite at the level to be
writing patches for the Python distribution, but your pointing me to
the base64 mod has certainly been helpful. Only problem now is I'm
getting a response of '501 Invalid AUTH reponse' after I send the
password, and I'm not sure why. There seem to be LFs tacked on to the
end of my login info, and I'm wondering if that is the problem. Any
other insights would be appreciated. Here is the output, and my code
follows.

OUTPUT:

send: 'auth login\015\012'
reply: '334 VXNlcm5hbWU6\015\012'		<-- 'Username:'
reply: retcode (334); Msg: VXNlcm5hbWU6
send: '[xxxxxxxxx]\012 \015\012'		<-- (my username)
reply: '334 UGFzc3dvcmQ6\015\012'
reply: retcode (334); Msg: UGFzc3dvcmQ6	<-- 'Password:'
send: '[xxxxxxxx]\012 \015\012'		<-- (my password)'

PYTHON CODE:

    fromaddr = "ehlen at flashcom.com"
    toaddrs = recipient
    msg = "This is a test"     
    server = smtplib.SMTP(SMTPServer)
    server.set_debuglevel(1)
    server.docmd('auth', 'login')
    server.docmd(username)
    server.docmd(password)
    server.sendmail(fromaddr, toaddrs, msg)
    server.quit()
    print "Done."
