Hello,

is it at all possible, possibly without modifying the source code of Dovecot, to enforce that a mailbox gets the NOSELECT attribute?

I have a namespace set up like this:

namespace private { separator = / prefix = Local Folders/ location = maildir:/xyz/core/store/maildir/%u/ inbox = yes hidden = no list = yes subscriptions = yes }

And the folder hierarchy my client builds based on the LIST response from Dovecot comes out as:

INBOX Local Folders <--- (standard flags, but no NOSELECT)

• Folder 1 -- Folder 1.1
• Folder 2
• Sent
• Trash Public Folders <--- NOSELECT
• Announcements

That's how I expect it, except that I don't want "Local Folders" to be selectable. When I select it and list the contents, I get the contents of INBOX. I have no clue why that happens. :-/

For the public namespace, everything works as expected, so I'm lost.

Basically: I want "Local Folders" to be like "Public Folders" and have \NOSELECT.

In maildir_storage.c I can find places where a MAILBOX_NOSELECT flag is set, but from what I understand that's only done if the path is not a directory or if the permissions are insufficient.

Random taking away of permissions on folders didn't yield the result I wanted. Either it resulted in no change, or in Dovecot complaining that the permissions were now too restrictive.

Forgive me if I missed something obvious. I only studied the source using grep and nano for 10 minutes before adding an ugly hack in my client to fake that Dovecot gave the "Local Folders" mailbox the NOSELECT attribute (my client is the only one that will ever talk to my installation of Dovecot, so I can do that). The wiki also didn't mention anything on NOSELECT. Google searches didn't help either.

I'd much rather have Dovecot give the response I want, rather than bending its responses around in my client.

Any ideas how I can achieve that?
