We can use the home directory of each user's mailhost account for many but not all users. Ideally, this system would run with no manual intervention. When a user's home directory is changed, we will need to ensure that the account on users changes, but this should take little more effort than is currently required to change home directories. By maintaining a single directory and exporting it via NFS, there should be no need for manual changes and rdisting. This information is maintained by Kyler Laird.
Constructive feedback is welcome.
