[Twisted-Python] SMTP authentication

[Sarah Addis]

Ok.. so I have found this piece of code in my smtp.py file:

    def _registerAuthenticators(self):
        # Register Authenticator in order from most secure to least secure

self.registerAuthenticator(CramMD5ClientAuthenticator(self.username))
        self.registerAuthenticator(LOGINAuthenticator(self.username))
        self.registerAuthenticator(PLAINAuthenticator(self.username))

so if I switch the order around to put PLAINAuthenticator first will this
hopefully work?
