Hi!

When syncing mailboxes from other server, you should use migration config file,
which has **no** auto=subscribe or auto=create folders, as these can mess up
with synchronization.

Please see https://doc.dovecot.org/admin_manual/migrating_mailboxes/ for more
details.

Does a migration config file specified with doveadm -c <file> add to and 
overwrite the existing Dovecot configuration for the time the command 
runs, like the -o options, or do I need to start a separate server with 
a full configuration to e.g. have my authentication and mailbox location 
available?
