Problem listing folders and subfolders

[Michael Menge]

Hi,

Quoting Jukka Huhta <jukka.huhta at helsinki.fi>:

> In Cyrus 2.3.16 (and earlier, don't know about 2.4 yet), there seems
> to be a problem listing subfolders in a following case. When a user
> has folders named like this:
>
> * LIST (\HasNoChildren) "." "INBOX.subfolder"
> * LIST (\HasNoChildren) "." "INBOX.subfolder 2"
> * LIST (\HasNoChildren) "." "INBOX.subfolder.subsub1"
> * LIST (\HasNoChildren) "." "INBOX.subfolder.subsub2"
>
> The space character (in "subfolder 2") seems to be sorted before dot
> (hierarchy separator) so that Cyrus thinks that "subfolder" has no
> children. After deleting/renaming "subfolder 2" the listing works as
> expected:
>
> * LIST (\HasChildren) "." "INBOX.subfolder"
> * LIST (\HasNoChildren) "." "INBOX.subfolder.subsub1"
> * LIST (\HasNoChildren) "." "INBOX.subfolder.subsub2"
>
> In some mail clients, namely IMP, the second level subfolders
> disappear totally when Cyrus declares that the parent folder
> "HasNoChildren". We have several reports from confused users who have
> "lost" their subfolders mysteriously.

> I didn't find any earlier discussions about this, but can anyone

Have a look at improved_mboxlist_sort in the man page of imapd.conf
