What are the rights permission to 3 subdirectories in /home/user/Maildir

in my /var/log/maillog I read:

Jul  2 00:18:54 brama postfix/local[30123]: 04E164E5754: to=<

failed: create /home/zulus/Maildir/tmp/

Looks strange, but 0001 with the correct user and group rights suffice
with postfix an maildir.

If the maildir didn't exist below the subdirectory, postfix will create
it automatically with the right permissions.



1. NFS for Dual Postfix Maildir Store


I have searched for a good answer to this to no avail.  There seems to
be a lot of conflicting info.  I posted in a couple Postfix groups and
got zero response, so I'm posting here hoping for better feedback.

I have a RHEL 4.5 box running Postfix+Dovecot+MySQL.  I have about
about 3200 accounts in 1200 virtual domains and maildir spools.  There
is an average of 50-60 emails/minute received during peak periods, and
as a company we are growing at a rate of about 20%/year.

I would like to put an identical RHEL box running Postfix+Dovecot
+MySQL +SquirrelMail into operation, DNS round robin'd.  I would like
to mount my spool directories on an NFS share to a third RHEL server
with a screaming fast RAID10 volume.

I have read posts regarding problems with NFS locking, but am not
certain whether it applies only to mailbox spools or both mailbox and
maildir.  I have read of ways of possibly avoiding locking issues by
using fcntl() locks.  I have read posts saying it's good, it's bad,
etc. this possible, good idea, bad idea?  Is there a definitively
better way to do this with something other than NFS?  Will I run into
any Dovecot issues?

Obviously I'm not doing anything that hasn't been done already, but
Google isn't giving me info I can feel confident of.  I would
appreciate any comments.  Thanks!
