- If I remember correctly, root permission isn't required; /bin/mail (the
- delivery agent) is setgid mail so that it can write to users' mailboxes.
-
- If you're going to do this, make absolutely sure that all mail delivery is
- done on the machine with the physical disk containing the mail directory.
- Even then, you might have problems. NFS locking is notoriously unreliable;
- There are situations where you will lose mail with this setup.
-
- A better solution would be to use a specialized protocol for accessing these
- centralized mailboxes, such as POP or IMAP. Servers/clients available at
- your favourite Internet archive site; ask Archie for details.
