- Sure it does. You just need to think about it a little bit beforehand.
-
- First and foremost, to avoid the problems with locking, permissions, etc. etc.,
- make sure any given user's mail is only *delivered* to one system - preferably
- the one serving /var/spool/mail, since that's the most efficient and totally
- avoids any delivery locking problems.
-
- This can easily be accomplished using a global alias table which is propagated
- nightly (or whatever) by a cron job. This has been in use here for years, and
- it's wonderful.

- Ah, AIX is doing it differently from the rest of the world. Well, if you can't
- make AIX do it "right", you can make the Suns adapt to it. Or you can avoid all
- the conflicts by having the mail server do the delivery.

-
- So create one - what's the big deal? On AIX mail is group 6; on Suns group 6
- is news. If you don't run news on your Suns, this doesn't matter. If you do,
- news really doesn't care which group number it uses, just change it.
-
- I was going to address all your points one by one, but the message was too
- long (I'll email it if you want, though). They're all easily worked around,
- and when I got to the end I realized that you're 90% of the way to having a
- central mail spool work nicely anyway, with your combination of NIS aliases
- and hiding originating addresses. The only remaining step is to have every-
- one's mail delivered on the existing mail hub and then mount its spool area
- everywhere through NFS.
