Many thanks for your reply. I realized that the title of my email was not explaining my exact problem. My problem is not the creation of the folders. I am happy with the folders created by RoundCube. I am confused why Outlook can't write to the Sent Items folder. Logically Outlook, TB or any other email client must have permission to write the sent mails to the chosen sent mail folder on an IMAP server without any problems. Am I wrong?
So Outlook doesn't give any error, just doesn't write the mail to the intended folder? I think it's Outlook configuration problem. There is nothing on Dovecot's side that you can do anyway. (Unless there's something really wrong, and in that case Dovecot should log error message about it.)
