Backup of newly registered ID fails

I am getting the following error when I register people. The only thing I have changed is that I changed some routing upstream (another server) and removed the “smart host” option on this server (this machine knows everything now, but does pass internet mail to a gateway machine non-local domains). Any ideas where to fix this? I’ve never seen it before.
