🪲: importing mails from dovecot works but they are missing

[famfo]

What happened?

After importing mails from dovecot with stalwart-cli -u <url> import messages -f maildir-nested <account> <maildir path>, they start using storage space in the account but do not show up over an IMAP login. The sub-folders also do not show up.

How can we reproduce the problem?

1. create a nested maildir with dovecot
2. import the mails

The CLI is going to be removed in v0.16 and replaced with a new tool. Please using imap-sync in the meantime.

@mdecimus it seems new tool for importing messages and other stuff is https://github.com/stalwartlabs/vandelay/ , right?
2. Should I use Vandelay instead of stalwart-cli -u import message for importing emails from old Dovecot server backuped folders?
3. Does Vandelay support importing whole maildir with lots of subfolders, or it imports only "cur new tmp" messages from only 1 folder at a time?

[mdecimus]

1. Correct
2. Yes, stalwart-cli only handles server settings, not user data.
3. It imports the entire Maildir structure.
