[Twisted-Python] SMTP with authentication

[Alvin Wang]

I modified this example
http://twistedmatrix.com/projects/mail/documentation/tutorial/smtpclient/smtpclient-7.tac

I am still not completely clear on what is happening

Thanks for the help
Alvin

from twisted.application import service

application = service.Application("SMTP Client Tutorial")

from twisted.application import internet
from twisted.internet import protocol
from twisted.mail import smtp
from twisted.mail.imap4 import CramMD5ClientAuthenticator

class SMTPTutorialClient(smtp.ESMTPClient):
    mailFrom = "from at sender.com"
    mailTo = "to at dest.com"
    mailData = '''\

Hello, how are you, goodbye.
