[Twisted-Python] stmp client with multipart

Fri Mar 28 14:36:11 MDT 2014

How can I get something similar into a smtp client 12? multipart message

    fn = "example.mp3"
    multipart = MIMEMultipart('alternative')
    multipart['Subject'] = 'Tutorate!'
    multipart['To'] = 'Selfie'
    multipart['From'] = 'Selfie'

    text = "Hello, how are you, goodbye."
    textpart = MIMEText(text)
    multipart.attach(textpart)
    htmlpart = MIMEText("<html>" + text + "</html>", 'html')
    multipart.attach(htmlpart)

    part = MIMEBase('audio', "mp3")
    part.set_payload( open(fn,"rb").read() )
    Encoders.encode_base64(part)
    part.add_header('Content-Disposition', 'attachment; filename="%s"' %
os.path.basename(fn))
    multipart.attach(part)

    io = StringIO.StringIO()
    g = Generator(io, False)
    g.flatten(multipart)
    v = io.getvalue()

    class SMTPTutorialClient(smtp.ESMTPClient):
        mailFrom = "mg_selfie@ <mg_selfie at scewpt.com>"
        mailTo = "mg@ <mg at scewpt.com>"
        def getMailFrom(self):
            result = self.mailFrom
            self.mailFrom = None
            return result

        def getMailTo(self):
            return [self.mailTo]

        def getMailData(self):
            print v
            return StringIO.StringIO(v)

        def sentMail(self, code, resp, numOk, addresses, log):
            print 'Sent', numOk, 'messages'

            from twisted.internet import reactor
            reactor.stop()
