What are these mailboxes?

Arbitration mailboxes:

The arbitration mailbox is used to store the original message that’s awaiting approval. By default, one arbitration mailbox is created for moderated transport during setup. It’s used for all moderated recipients. You can add additional arbitration mailboxes for load balancing purposes. If you’re using multiple arbitration mailboxes, you need to specify which mailbox to use for each moderated recipient.

  1. I upgraded to CU6 a couple of weeks ago and I just happened to look in the health mailboxes OU and there are 40 objects in there. I know I can delete them and restart the service, but I’m curious as to why so many are there in the first place. Thoughts?
