dovecot - Jun 2012 - Dovecot Maildir - How to Seperate mail folders

Hi Timo,

thank you very much for your quick reply. I tried that but it is not possible to
SELECT such a mailbox.

I have in dovecot.conf:
---
mail_location=maildir:/data/messages%h

namespace private {
  separator = /
  prefix   location = maildir:/data/messages%h
  inbox = yes
  list = yes
}

namespace public {
  separator = /
  prefix = greetings/
  location = maildir:/data/greetings%h
  inbox = no
  list = yes
  hidden = yes
}
---

Messages are coming in from EXIM separated by a special HEADER into this two
folders.
For INBOX this works fine but not for greetings, although the maildir files are
being created upon delivery.

Sample IMAP Session AFTER delivering a greeting-type message:

---
01 OK Logged in.
>> 02 list "" "*"
* LIST (\HasNoChildren) "/" "INBOX"
* LIST (\Noselect \HasChildren) "/" "greetings"
* LIST (\HasNoChildren) "/" "greetings/INBOX"
02 OK List completed.
>> 03 select "greetings/INBOX"
03 NO Mailbox doesn't exist: INBOX
>> 04 select greetings
04 NO Mailbox doesn't exist: greetings

---

What is this "\Noselect" mailbox showing up and why is it saying
"greetings/INBOX" in the third row when in fact there isn't a
mailbox with this name?

I am very sorry for having to bother you again, but I don't know what we are
doing wrong here.
(Dovecot version is 1.1.16)

You should be able to do this with namespaces.

namespace {
  prefix = INBOX/VeryImportantMessages/
  location = maildir:/very/important/messages
  hidden = yes
}

------------------------------

Thank you. Can you tell me if this bug belongs to the LIST command only?
Or is it generally impossible to SELECT such mailboxes with this version?
