This can be closed, this turned out to be a permissions problem. I had both Ubuntu and Centos mail servers, ubuntu wants the list files to have a group of "list", and Centos "smartlst". I had them NFS mounted across several servers. It was the different OS's fighting over what GID these files should be that caused the problem. I moved the last CentOS server to Ubuntu, set the group ID's to "list", and now everything is good. This bug can be closed.
