Blocking one student from emailing another student

[panderson]

I thought I knew how to do this, but I guess I either forgot or didn't know.  Can anyone tell me how I can block student A from emailing student B (or both users from emailing each other, while still maintaining their ability to email other students?  Thanks!

Gmail -> Routing Filtering on the OU where the students sit or at the Root OU. You have two rules, one going to the other, and the other going to the one. You may be able to affect both them in one Rule using Internal - Sending/ Internal -Receiving

 Gmail content compliance rule (apps/Workspace/Gmail/compliance) should do the trick.

Create a new compliance rule, check all boxes in step 1, step 2 (expressions) you need to add an advanced content match where location is "sender header" , match type is contains text, and content is the student1's email address.  You'll need to add another advanced content match choosing "recipient header" and specifying student2's email address. Step 3 choose REJECT message, then save.

You'll then need to create another compliance rule REVERSING the email addresses from the first rule, as the first rule only handles sending from student1 to student 2.
