Jeff,

Thanks for the reply.  I wish I could say that to my users however I did a
test while on the phone to my ISP.  I sent a hotmail to the ISP and cc'd it
to myself.  The ISP got it within seconds but my copy never got through.

Watching the packets come through the network, shows that the qube is
receiving an attempt by the hotmail server to connect, but nothing more
happens.  The packet details shows an SMTP command that is "unknown" but I
don't know enough why.

Any other thoughts on this would be very appreciated.
