[Dovecot] Dovecot NFS Indexes and IMAP Migration

[Jan van den Berg]

FYI,

We deployed Dovecot 1.1RC1 yesterday on about 100k+ mailboxes (on
multiple frontends which connect to a storage via NFS).
We handle about one IMAP login every second (for now only from our
webmail app). So far; it's been running like a charm; we come from
Courier IMAP and Dovecot IMAP (with indexes and auth_cache) performs
much faster and puts less load on our frontends and webmail app.

Cheers,

Jan

v1.1 is already used in production in a couple of large installations,  
so it should probably work quite well. I think most of the crashfixes  
that are on my TODO list happen only after client has already  
disconnected.
