Dovecot migration to new server with namespace issues

Hello,

I'm trying to migrate old ispconfig server with dovecot + postfix to a new modernized server. I'm having some trouble with dovecot doing what I want/need to reuse use my old configuration. I've been using maildir++.

The new dovecot makes me some headcache as I cannot simply reuse the old configuration or INBOX folder. Any ideas how to get this fixed?

My Maildir's & IMAP looked like this for the old system:

Maildir/  <-- obviously not shown in IMAP :) INBOX/ Drafts/ Templates/ Sent/ Archives/ Trash

On my old ispconfig server with older linux/dovecot version I simply had this configuration:

namespace inbox { inbox = yes

  mailbox ".Drafts" { auto = no special_use = \Drafts } mailbox Drafts { auto = subscribe special_use = \Drafts }

  mailbox ".Junk" { auto = no special_use = \Junk } mailbox Spam { auto = no special_use = \Junk } mailbox Junk { auto = subscribe special_use = \Junk }

  mailbox ".Trash" { auto = no special_use = \Trash } mailbox Trash { auto = subscribe special_use = \Trash }

  mailbox Archives { auto = subscribe special_use = \Archive } }

My approach to make this work using dovecot 2.3.21 got me in some trouble. Obviously new dovecot wants to store INBOX-Date in Maildir/{cur,tmp,new} instead of Maildir/INBOX?

I've tried with this configuration - which at least correctly shows INBOX-Data now in my IMAP, but I also have some troubles:

Maildir/  <-- obviously not shown in IMAP :) INBOX/ My Custom Folder/ Drafts/ <------------- repeating from imap-root subscribing it there duplicates it here :-/ Templates/ Sent/ Archives/ Trash .Trash Drafts/ Templates/ Sent/ Archives/ Trash .Trash (somehow same than Trash, only want Trash non-dotted)

New configuration approach:

mail_location = maildir:/var/vmail/%d/%n/Maildir/:LAYOUT=fs:DIRNAME=/:maildir_copy_with_hardlinks=yes maildir_copy_with_hardlinks = yes

plugin { mailbox_alias_junk1 = Junk mailbox_alias_junk2 = Spam

  mailbox_alias_sent_de = Gesendet }

namespace { type = private separator = /

  location = maildir:/var/vmail/%d/%n/Maildir/:LAYOUT=fs:DIRNAME=/:LISTINDEX=

  inbox = no list = yes subscriptions = yes

  mailbox .Junk { auto = no special_use = \Junk }

  mailbox .Drafts { auto = no special_use = \Drafts }

  mailbox .Trash { auto = no special_use = \Trash }

  mailbox .Sent { auto = no special_use = \Sent }

  mailbox .Archives { auto = no special_use = \Archive }

  mailbox .Templates { auto = no } }

namespace inbox { type = private separator = / prefix = INBOX/

  location = maildir:/var/vmail/%d/%n/Maildir/:LAYOUT=fs:DIRNAME=/

  inbox = yes list = yes hidden = yes subscriptions = yes

  mailbox .Junk { auto = no }

  mailbox .Drafts { auto = no }

  mailbox .Trash { auto = no }

  mailbox .Sent { auto = no }

  mailbox .Archives { auto = no }

  mailbox .Templates { auto = no } }
