Pkg exim4 users - Nov 2011 - tls errors when using outlook as client and smtp auth on exim server

I have smtp auth enabled on my Exim server on Debian Squeeze. I am trying to
connect using Outlook 2010.

In my /etc/default/exim4 file, I have the following.
SMTPLISTENEROPTIONS=''-oX 465:25 -oP /var/run/exim4/exim.pid''

I aslo have TLS enabled

# Enable TLS
MAIN_TLS_ENABLE = true 

But, it is giving the following error.

2011-11-15 18:42:10 TLS error on connection from
173-228-81-232.dsl.static.sonic.net [173.228.81.232] (gnutls_handshake): A TLS
packet with unexpected length was received.

What do I need to do to get Outlook 2010 to work as a client?

Thanks,

brian
