Getting errors from Imaplib

[Beatrix Willius from Moth Software]

Hi,

first poster here. I still consider myself pretty much a Python newbie.

Let's say I have the following very simple Python code:

import imaplib

host = 'imap.gmail.com'
try:
    imap_connection = imaplib.IMAP4(host)
    print('success')
except imaplib.IMAP4.error:
    print('authentication failed')

Now, Gmail doesn't like non-ssl connections. In this case I only want to return an error. This worked for Pyhton 2.7 but in Python 3.4 I only get a traceback (see below). The line print('authentication failed') is not executed at all. How do I capture the error for using the print function?

Mac OS 10.10. Python 3.4.1. The script is part of a larger one that is talking to my Xojo application.

Connected to pydev debugger (build 135.1057)

    self.sock = self._create_socket()
