Thanks for your response... I tried telnet and was able to connect to the smtp server on the desired ports but it wasn't until firing up wireshark, I was able to find out that things were going wrong for during the TLS authentication. Perhaps on my work network (the one which worked for me) either did something to fix it or made CB think that it wasn't available.
I will explore further into how to properly setup my TLS for use with CB and perhaps write a blog post or wiki entry to document it. Cheers, PS - my home ISP was blocking port 25 as I was able to telnet on that port. But switching to port 587 solved that problem.
