I've added the imapc config to local.conf, and I run it like this: doveadm -Dv sync -1 -R -u local_user -m mailbox_name imapc: (or variations on that, e.g. with -n namespace). It successfully logs in to the remote imapd, but doesn't decide to transfer anything. If I leave off the "-m mailbox_name" it does start traversing the remote maibox hierarchy, but I really don't want it to transfer everything --- just some specific mailboxes. One thing that's unclear to me is exactly what strings I should pass to the -n and -m flags. Do I specify a namespace by its local prefix, or its remote prefix, or its name in the config file, or ... ? And mailbox names? How does dsync map remote to local names?

That probably reveals what goes wrong in the session. Sami
