[RCU] Special IMAP Folders "Sent vs. sent-mail"

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).

/#doveadm mailbox list -u user@test.com/ /INBOX/ /INBOX.Trash/ /INBOX.Sent/ /*INBOX.sent-mail*/

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';*/

Is this a configuration issue? How do we tell rc to use the existing mailbox INBOX.Sent ?

Thanks for clarification plataleas
