I have an ongoing problem at the school where I work with email. The staff at school need to be able to send to distribution groups. This is all set up and working correctly. However, when the pupils at the school have access to these distribution groups, they begin to abuse the lists and send inapporpriate emails to each other and occasionally members of staff.
Is there a way I can deny the GAL to the students? Or any other advice would be greatfully received.
