2.3.1 -> "doveadm backup -A" not working

Hi,

I'm running 2.3.1 and trying to do a backup. Wiki and manpage showes that -A will backup all mailboxes.

It seems that "doveadm -Dv backup -A mdbox:/mnt/BACKUP/DOVECOT/" is saving each mailbox to " /mnt/BACKUP/DOVECOT/" but after finishing one, its overwriting the data from the previous user. So it ends with only the mails from the last user processed.

I tried %u but thats not recognized and used as String in the path.
