dsync(jedi at example.com): Error: Failed to sync mailbox Drafts: STATUS 
cannot access mailbox Drafts
dsync(jedi at example.com): Fatal: dsync backup: Looks like you're trying 
to run backup in wrong direction. Source is empty and destination is not.

To be clear, I am trying to pull all the mailboxes from the old server 
on to this dovecot server, which has no mailboxes populated yet. It 
looks like this command would be pushing the messages from here to the 
imapc_host rather than pulling?
