Sent messages are currently directed to the Sent Messages folder not Sent Mail folder.
Why are there two folders listed?
I amended /etc/dovecot/conf.d/15-mailboxes.conf and commented out Sent Messages, moved existing messages from that folder to Sent Mail, applied configuration. Then stopped and restarted Dovecot. Finally, I rebooted the server to apply the new configuration. None of these worked and the two folders still show and messages still go to the Sent Messages folder.
I do not mind which is shown but how do I set it so only one shows and all the sent mail goes to it?
