	That fixed some errors, but it still is having some sort of trouble
with that command:

# time doveadm -o mail=maildir:/home/bu/user.mdbox import -u
user at domain.com maildir:/home/users/user%domain.com/Maildir/ "" all
doveadm(user at domain.com): Error: Can't find namespace for mailbox Trash
doveadm(user at domain.com): Error: Can't find namespace for mailbox test
