[Dovecot] How can I put a file back in Maildir folder?

Hi,

I have a problem: today, when I ran "fsck" some file was linked to "lost+find" folder... After some hours I has all files mapped (File / User). So... how can I put this files back in Maildir folder of this users?

I tried with: cat $file | deliver -d username

but without success...

Any help will be appreciated!

Thanks!
