Hello, Timo. Wow. directly from the creator ;-)
Thanks for the reply.
This is something completely new.
We are connecting to our pre-existing custom-made mail server.
IMAP needs to be plugged into the infrastructure.
So basically we can simply use existing index_* since we need to have
index files (on local fs) no matter what.
I saw dbox source file there. Is the layer stable (as far as API goes)?
Tell me more about the abstraction layer.
Thanks a lot!!

We are trying to develop a non-filesystem backing store.
So basically we do not store mailboxes for users in local
filesystem. We do RPC call
to fetch from fileservers.
Well, the best there exists currently is http://dovecot.org/list/dovecot/2007-November/026632.html
but it's for an old Dovecot version. You really should start with
Dovecot v1.2.
Do you need to use some existing mail database or is it something
completely new? I'm just wondering if my upcoming dbox filesystem
abstraction layer would help you.
Anyway, basically just go and look at lib-storage/mail-storage.h and
mail-storage-private.h and mailbox-list.h and mailbox-list-
private.h. Implement those using your RPC calls, using index_*()
functions wherever possible, just like the filesystem backends. You
can also make Dovecot use in-memory indexes only with your database,
although it probably would be better to just create them on local
disk and act as kind of a cache.
