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.

Most likely that mailbox exists like that in the filesystem. It shouldn't. Dovecot hasn't allowed creating those for several years now.

In the filesystem the mailbox is in mUTF-7:

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

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..

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!
