Just for the record:
As I expect most of you are aware I've handed off the duties of managing the mailing lists to Marcus and I've been communicating with him to ensure he is able to manage this. In the past he has had an ssh key under the root account giving him root access to box2. He decided that he had misplaced the matching private key and he sent me a new public key. I deleted the old key and installed the new one in /root/.ssh/authorized_keys
