Migrating from maildir to mdbox

[Felix Rubio Dalmau]

Hi everybody,

	I have a virtual user setup that is using maildir, and I'd like to migrate it to mdbox. Following directions from 

		http://wiki2.dovecot.org/Migration/MailFormat

	and keeping in mind that my maildir is in  maildir:/mnt/vmail/%d/%u, after having updated 10-mail.conf I have tried to execute:

		dsync -u "user at domain.org" mirror maildir:/mnt/vmail/domain.org/user

	But it replies this answer, that I do not understand:
	
		dsync(user at domain.org): Error: Mail locations must use the same virtual mailbox hierarchy separator (specify separator for the default namespace)

	What am I doing wrong?

	Thank you,
	Felix
