Hi, after upgrading from Dovecot v2.3.13 to v2.3.14 I realized that shared sub-folders, e.g. "Lieferanten/Rechnungen", cannot be accessed anymore, although the underlying configuration hasn't been changed at all. If I try to access such a folder using e.g. Thunderbird the error "Invalid mailbox name: Name must not have '/' character." is shown instead of opening the folder.
Now I wonder if this is a bug or feature or what need to be done to get the previous function back.
In the change notes of the latest Dovecot version I found the following point, which might be the root cause of the problem:
- If BROKENCHAR or listescape plugin is used, the escaped folder names may be slightly different from before in some situations. This is unlikely to cause issues, although caching clients may redownload the folders.
These are my shared folder configuration parameters:
namespace { location = maildir:/home/imapshared:INDEXPVT=~/.imapmail/shared prefix = "#Shared/" separator = / subscriptions = no type = shared }
protocol imap { mail_max_userip_connections = 15 mail_plugins = " listescape" }
I also checked how the shared folders are returned with both Dovecot version and cannot find any difference in the naming, except that the v2.3.13 correctly labels one folder as "\HasChildren", which v2.3.14 doesn't?!
v2.3.13:
a list "#Shared/" "*"
* LIST (\HasChildren) "/" #Shared/Lieferanten
* LIST (\HasNoChildren) "/" #Shared/Lieferanten/Rechnungenv2.3.14:
a list "#Shared/" "*"
* LIST (\HasNoChildren) "/" #Shared/Lieferanten
* LIST (\HasNoChildren) "/" #Shared/Lieferanten/RechnungenAny help/hint is highly appreciated.
