[Dovecot] Accessing maildir snapshots through dovecot

[Laurent CARON]

Hi,

I'm currently having a fairly simple setup:
- users (real, not virtual) 
- Maildir storage (over NFS)
- 1 namespace

I'm currently trying to render the storage snapshots available through
dovecot (to allow my users to browse their mail history).

dovecot.conf:
namespace {
  inbox = yes
  location =
  prefix = INBOX.
  type = private
}


I did the following modifications:
dovecot.conf:
namespace snaps-h0 {
  prefix = INBOX.EmailBackup.h0.
  hidden = no
  list = yes
  inbox = no
  location = maildir:/home/.snapshot/hourly.0/%u/Maildir:INDEX=/var/tmp/dovecot/indexes/hourly.0/%u:CONTROL=/var/dovecot/control/hourly.0/%u
  type = private
}

Problem: 
I don't see the content of the inbox folder contained in the snapshots
(subfolders are perfectly viewed).

Do any of you have a clue on how to render it visible ?

Thanks

Laurent
