Deleted mailboxes but ctl_mboxlist still shows them

Hello,

i deleted some (autocreated) mailboxes with cyradm:

sam user.$ACCOUNT myadmin all
dm user.$ACCOUNT

However, they still seem to be in the mailbox list

/usr/lib/cyrus/bin/ctl_mboxlist -d |grep zzzuedth2iqa2
user.zzzuedth2iqa2      16 (null)
user.zzzuedth2iqa2.INBOX        16 (null)
user.zzzuedth2iqa2.achive       16 (null)
user.zzzuedth2iqa2.spam 16 (null)
user.zzzuedth2iqa2.trash        16 (null)

cyradm shows them, too with lm user.*

How do i delete them?

I tried
- reconstruct user.*

and

ctl_mboxlist -v /var/lib/cyrus/mailboxes.db

which shows:
'user.zzy7voro59endm6i.spam' has a DB entry but no directory on
partition '(null)'
'user.zzy7voro59endm6i.trash' has a DB entry but no directory on
partition '(null)'
'user.zzzuedth2iqa2' has a DB entry but no directory on partition '(null)'
'user.zzzuedth2iqa2.INBOX' has a DB entry but no directory on partition '(null)'
'user.zzzuedth2iqa2.achive' has a DB entry but no directory on
partition '(null)'
'user.zzzuedth2iqa2.spam' has a DB entry but no directory on partition '(null)'
'user.zzzuedth2iqa2.trash' has a DB entry but no directory on partition '(null)'

Any hint on this?

Thanks,
Michael
