[Dovecot] Question about dovecot 2.2 and LIST command

I am running dovecot 2.2 changeset 16983:d925674c4329 on AIX. We use mbox files with the "/" delimter. I have an imap protocol question. When I do:

1 list directory1/ * 1 OK List completed.

Is that the correct answer?

If I do 1 list "" *

it shows

• LIST (\Noselect \HasChildren) "/" "directory1"

I forget why I think that even with the delimiter, I should see some information about it. Is this a silly test that no imap client does?

Thanks, Jonathan
