dovecot - Jan 2013 - load sbub-mailbox

Hi,

We're about to migrate to dovecot (2.1.7 on wheezy), and I have a 
question about mail migration.

Our 'old' imap mailserver will remain available, and has the same 
usernames/passwords as our future dovecot mailserver.

The question: Is there an easy way to make the old mailboxes available 
under a subfolder (for example 'oldmail') in the mailboxes on the new 
mailserver?

A bit like mounting an old homedirectory under an 'oldfiles' directory 
on a new fileserver.

This way our users could access/migrate whatever folders they choose 
themselves, and we would not have migrate all messages to dovecot using 
scripts like imapcopy, etc.

Perhaps using the proxy functionality..?

Hope I make myself clear...?

Regards,
Mourik Jan

I would try to create a private namespace "oldmail"
http://wiki2.dovecot.org/Namespaces
with an imapc proxy
http://wiki2.dovecot.org/HowTo/ImapcProxy

I didn't test it, but configuration could look like this:

imapc_host = oldmailserver
namespace {
  type = private
  separator = /
  prefix = oldmail/
  location = imapc:
  inbox = no
  hidden = no
  list = yes
}

Daniel
