Not to pick on you, Graeme, but I just cannot believe that almost TEN YEARS LATER that this belief that "NFS is bad for mailboxes" persists.
OK, I'll add the caveat that in _my experience_, NFS is bad for mbox or other file-based mailbox formats in situations where there are multiple NFS clients (read: SMTP, IMAP and POP servers in a load-balanced farm) doing simultaneous delivery and client reads via IMAP4 or POP3. To expand a little, I've personally never deployed a single production mailbox on an NFS backend where there weren't multiple frontends in use!
We solved it a decade ago, folks... true, NFS locking has never been easy or pretty, but with care it could work. Perhaps with NFS v4's locking support people will finally start to reevaluate those old NFS prejudices?
Hrm... on a personal note this is about the only NFS "prejudice" I have - and you've now blown it out the water ;-)
Just one fairly nasty side-effect of maildir format on filers: the 4K block size.
I'll keep an eye on that. Thanks.
