Exchange Server 2003 permissions on emailing groups?

In school I have a Pupils email group and a Teachers email group. I want to prohibit pupils from being able to email their group, whilst allowing teachers to do so.





Any help much appreciated!

In the properties for the Pupils group | Exchange General tab, the default message restriction is "From everyone" - change to "Only from" and add the Teachers group
