[Dovecot] indexes?

[David Lee]

Picture:  A set of very similar UN*X IMAP servers all NFS-mounting their
INBOX area (traditional Unix format) from a common "/var/spool/mail"
area; activity for any given user ought to be within one box although this
cannot be 100% guaranteed.  There is the risk of multiple simultaneous
access (e.g. simultaneous LDA/delivers; simultaneous LDA/deliver and
user-driven IMAP update; etc.).  So locking is an important consideration.
Decent "noac,actimeo=0" seems to address this succcessfully.

But indexes...

What is the best place for the index files?  Logically alongside the INBOX
area on the shared-NFS area?  Or within each UN*X machine?  (Or something
else?)  And why?

Is there documentation of what functionality the index files provide, and
how, if at all, this interacts with the locking of INBOXes (and folders).

Thanks.
