reconstruct problem

[Luca Tolomelli]

I have this problem with the /usr/lib/cyrus-imapd/reconstruct -r -f
user.username

If I try to restore a mail that was saved on the cyrus server all work
as intended.

If I try to restore a mail that was saved on a NTFS (copying the mail
from the NTSF server to the cyrus server on the username directory) no
mail is shown (the owner of the restored mail is "cyrus").

What could it be?

Thanks
