Oh, sorry. I didn't even consider that it could have been broken for this long 
in v2.1.x without anyone noticing. Fixed:
http://hg.dovecot.org/dovecot-2.1/rev/a698fccd37c3

Time for v2.1.8 soon I guess :)

In the filesystem the mailbox is in mUTF-7:

# ls mailboxes/
Euro &IKw-/  INBOX/  Trash/

To create the LIST response from my example above you do exactly this:
convert the mailbox name to mUTF-7.

. LIST "" "INBOX.Euro &IKw-"
* LIST (\HasNoChildren) "." "INBOX.Euro &IKw-"

In file imap/cmd-list.c:

static int
list_namespace_mailboxes(struct cmd_list_context *ctx)
[...]
if (imap_utf8_to_utf7(name, mutf7_name) < 0)
i_panic("LIST: Mailbox name not UTF-8: %s", name);
[...]
imap_quote_append_string(str, str_c(mutf7_name), FALSE);

So maybe you could do this for the STATUS response, too?

Thanks for your help!

Most likely that mailbox exists like that in the filesystem. It shouldn't. 
Dovecot hasn't allowed creating those for several years now. There's no good 
way to handle that, because even if Dovecot translated it to mUTF-7 it couldn't 
access the mailbox because it wouldn't exist as mUTF-7 in the filesystem..

[Dovecot] UTF-8 mailbox name STATUS response

2012-07-02 Thread Ewald Dieterich 

STATUS in Dovecot 2.1.7 returns the UTF-8 decoded folder name in a
string literal:

. CREATE "INBOX.Euro &IKw-"
. OK Create completed.
. LIST "" "INBOX.Euro &IKw-"
* LIST (\HasNoChildren) "." "INBOX.Euro &IKw-"
. STATUS "INBOX.Euro &IKw-" (MESSAGES)
* STATUS {14}
INBOX.Euro € (MESSAGES 0)
. OK Status completed.

Is this intended? My Perl script based on Mail::IMAPTalk doesn't like
it and I wonder if there are other clients that don't cope with it.
