Subject: Migration dovecot server with local users to dovecot with virtual
mailboxes
Hello,
we are using a dovecot server with NIS, we want to transfer it to a new setup. As backend a mysql server will be used in the future.
My problem is, if I just copy the maildir or use "doveadm import" all mails are flagged as "unseen". How can i preserve the flags?
This is how I have tried it so far.
root@mail / $ doveadm import -s -u testuser@testdomain.local maildir:/tmp/testuser-maildir-230608/Maildir/:INDEX=MEMORY "" "All"
As a "workaround" I tried to change the flags.
root@mail / $ doveadm -v flags add -u testuser@testdomain.local "Seen" "ALL"
This led partially to the desired success, the mails are shown as "seen", but the folders (e.g. Roundcube) still show unread mails.
dovecot -n
