I need a little help to decide which works best for my situation here. We have a network that is not wired up to the internet at all, for security purposes. This our order processing and accounting network where we want to keep it completely away from outside access.

Our workstations are Windows XP Pro with Norton GoBack installed. This resets the workstations back to a preset state everyday to keep unwanted software and files off of the harddrives.

We are wanting to set up an internal email server so that people can email back and forth internally only. As well as still be able to access previous emails from the server. I was thinking of a email server where everyone logged in via a browser and could keep everything on the server.

Suggestions?

a combination of sendmail and squirrelmail would do the trick.

And also to add, a instant Message server as well. Which I am sure many would suggest Jabber.
