My dovecot stores users' emails on /var/spool/imap/<user> and stores the messages index on /var/lib/imap/<user>.

I have many users who do not yet have their userdb_home directories created on the server, because that is created at the time of first login.

I'm testing dsync for replication and have seen the following error:

dsync-server(<user>): Error: Couldn't create lock /var/lib/imap/<user>/.dovecot-sync.lock: No such file or directory

The /var/lib/imap/<user> directory does not exist yet and I think this is the cause. How can I avoid this error message?
