[Dovecot] dovecot through NFS

[Marten Lehmann]

Hello,

as our mail server load increases every day, I plan to scale the single 
mailserver in differnt units:

1x big storage server for all mailboxes, folders exported through NFS
1x smtp for mail-in (queue local, messages on storage server)
1x pop3/imap to retrieve the messages (config local, messages on storage 
server)

Since we're using maildir only, there's no problem to get the messages 
into the mailboxes. But what about dovecot for retrieving them? NFS will 
be v3. Is locking still a problem with it? Might the indexes get corrupt?

Regards
Marten
