Gnus in an Exchange Server environment with authentication

[Don Dwiggins <dond@advancedmp.com>]

I've been happily using Gnus for a while now in a corporate environment,
interacting with the Exchange server via POP and SMTP.  Recently, the
network admin made a change to Exchange that makes it impossible for me to
send mail to an outside address via SMTP -- I get something to the effect
that it can't relay the message (I had to get a newer version of SMTPmail.el
just to be able to talk to Exchange at all).  I suspect that it has to do
with Exchange using NT Integrated Authentication, which is how Outlook talks
to it.

I'm a Python developer, and have found that I can send messages using CDO
(Windows Collaboration Data Objects).  I'm thinking about writing a little
Python application that I can call from Emacs (possibly using Pymacs) to
send a message, but I'm not sure where to start on the Emacs side.

Any pointers toward this or better approaches appreciated.
