How difficult is it to set up an MH folder to be shared by multiple
users so that the following conditions hold:
- works under Ultrix (VAX 4.2bsd is close, if you don't know Ultrix)
- only members of a particular group may access the MH folder
- all simultaneous users of this folder get a consistent view of
its contents: e.g., if larry, moe, and curly are all using this
folder and moe decides to delete message 42, either
(a) both larry and curly must then see that message 42 has
been deleted, or even better
(b) MH marks message 42 for deletion in a way that lets
larry, moe and curly all realize that it's been so
marked, but only commits the deletion when the folder
is no longer beig read by anyone.
Also, new messages delivered to /usr/spool/mail/whatever are
automagically incorporated into this folder, and in addition,
if larry, moe and curly are currently using the folder, all 3
receive notification that new mail has arrived in this folder.
Is this asking for the impossible?
Thanks,
Mike Khaw
