I wish I had read some docs, I get the answer.

The reason is that Sent folder should be subscribe.

# /etc/dovecot/conf.d/15-mailboxes.conf auto = subscribe

hello,

I'm successfully send and receive emails by postfix and dovecot, but

folder name 'Sent' is gone, all sent emails are located in Drafts folder.

Anything wrong? Guess it has something to do with mailbox and location.

Here is doveconf -n

I also checked mail dir, it has /var/mail/XXX/Maildir/.send/

So anything wrong?

Thanks,
