Requires SMTP server to support TLS

[Nicholas Allen]

Due to a change in Python 2.6 the SMTP server is required to support TLS. This is because it now throws an exception instead of returning an error code. The fix was incorporated into the bzr-email plugin and the same fix should work for bzr-email-notifier too. (see bug 335332).

I used this to bypass STARTTLS if not available on the mail server

        # If this fails, it just returns an error, but it shouldn't raise an
        # exception unless something goes really wrong (in which case we want
        # to fail anyway).
        if self._connection.has_extn('STARTTLS'):
            self._connection.starttls()
            self._connection.ehlo()
