[mod.computers.vax] Multiple accounts with the same mail directory.

Bakin@HI-MULTICS.ARPA (Jerry Bakin) (03/11/86)

I would like to have n accounts have the same mail directory as
their default directory.  Naturally, since it is their default
directory, each account should have complete access to it.

First cut: (Use a big hammer) I brute forced a link (using set
file/enter) into each account pointing to the "correct" file.  I then
created an ACL so that those accounts had complete access to the file
and piss on everyone else.  Ok.  Worked fine.  Everyone (of importance)
DID have complete access.  Everyone (in the system) could send mail to
any of the accounts and anyone in the set could read/write/delete the
message.  One problem, as expected, the mailuaf entry became unsound.  I
had to terminate it.  Terminate it with extreme prejudice.  (I suspose a
batch job run once an hour could fix things up in this approach.)

Second cut: (When in Rome) I saw something about forwarding addresses in
sys$examples:mailuaf.com.  I even looked them up in help.  I even went
so far as to set n-1 of the accounts to forward their mail to the nth
account.  Ok.  Worked fine.  Anyone who sen mail to any one (i) of the n
had the mail automatically transferred to mailbox n.  Mailuaf kept its
cookies down.  One problem, unexpectedly (for me at least), for account
{j:[1,2,,n-1]}, j reading its mail DID NOT IMPLY j reading N's mail!
That is, "forward" implies forward only, not a link of the two mailboxes.

Third cut: (Ask the gurus)  Ok, does anyone have any ideas?  It is
possible that when I hammered all day and when I hammered all night
I hammered that file right out of its place, and its possible DEC 
doesn't support this, but it is certainly true that I have no idea
what's going on!

Thanks,
