hi all

clarification for special IMAP folder Sent is needed.

- We have user@test.com with the following initial IMAP folders:

#doveadm mailbox list -u user@test.com
INBOX
INBOX.Trash
INBOX.Sent

- The user@test.com logins to roundcube.

#doveadm mailbox list -u user@test.com
INBOX
INBOX.Trash
INBOX.Sent

- The user@test.com is composing an Email (without sending the email).

We would expect that rc is using the sent_mbox folder called "Sent" for storing Sent Mails:

#grep sent_mbox /etc/roundcube/defaults.inc.php
$config['sent_mbox'] = 'Sent';
