- I would just like to add that I also use MH on an NFS system where my
- mailbox is exported from the mail server. Initially I built MH without
- locking and everything went fine, then I rebuilt to include mime and
- decided to be a bit more careful in setting so I selected locking. This
- proved to be a big mistake as inc wouldn't always run. I am not trying
- to point the finger at inc, it seems that nfs is not particularly good
- at locking, IMHO opinion though it is better to put up with the
- occaisional duplicated mail than to lose your access to mail.
- Incidently mail itself had no problems. My system runs SunOS 4.1.1.
