mailbox reconstruct and empty inbox

[Riccardo Veraldi]

Hello,
a user has lost for mistake a part of his own emails

so I have restored all of them from tape to a different directory location
so the original user was

/var/spool/imap/u/user/user1

the restore went in

/var/spool/imap/u/user/user2

and I created s new cyrus user

cm  user.user

after this i reconstructed the new mailbox as cyrus user and also the quota

reconstruct -r -f user.user2

quota -f user.user2


the mailbox is reconstructed succesfully and I can see the dump with

ctl_mboxlist -d

i can see the new user.user2 mailbox with subfolders

the problem is that when I try to access to the new mailbox with IMAP 
client (thunderbird or whatever)
the mailbox is complitely empty

this never happened to me before

what can be  the issue ?

I am using cyrus-imapd 2.3.7

thank you


Rick
