If you haven’t tried Google Apps I can thoroughly recommend it – it is a brilliant tool for doing collaborative work including small group shared writing (several students can edit the same document in real time) and gathering lots of science data into a single spreadsheet (also in real time). Best of all – it is free to schools!
It is now possible to easily limit the email facility so students can only send internal mail (for safe guarding reasons). I have posted instructions before explaining how to use Google’s Postini service to quarantine mail heading to or from external email addresses. Google have now simplified and improved the ability to limit sending of emails outside the domain and this is how you do it.
Organise your users into groups
I put all my students in a single group (you could have groups for different year groups if you want some to be able to send email).

Configure the email restrictions from the Advanced Tools tasks
I have restricted the students group to only allow email to/from the domains I specify (you can add domains from partner/link schools here so they aren’t blocked).
Test
This is the error message my students get if they try to send email outside of the domain

That’s all there is to it – it is now easier than ever to control email to and from student email boxes. All we need now is a free message archiving facility Google!
