    Interscan can be made to work on the same machine as Sendmail. Using
    IP Filter or SunScreen you should be able to rig something. I'd say
    Interscan runs on port 25, and Sendmail listening only on localhost,
    maybe on a port other than 25. Email entering and leaving your
    network talks to Interscan. Interscan sends the email to Sendmail
    which then handles the details of where to send the email.

    This might get messy. To say the least.

    I have been running Amavis, via the magic of milter, happily for the
    better part of a year.

    I'd say if you don't want to run Interscan on another machine, you
    don't need Intrescan's performance, and the folks at Trend haven't
    offered any suggestions better than mine; go with Amavis. It will be
    simpler, *way* simpler.

    If you don't mind tossing a Linux (or Solaris) box into the mix, run
    your mail hub (sendmail) on the Linux box. Interscan can run how it
    wants to on your Solaris proxy machine, you can still use sendmail how
    you want to, DNS can be altered so your users are none the wiser, and
    everybody is happy.

    I don't understand where and why the NT box needs to enter the mix.
    But if you have one, it could be re-installed as a Intel Solaris or
    Linux box to function as I mentioned above.
