Retrieve mails from a folder

[kubitas]

Hi everyone! I apologize because my English isn't very good. I hope I can understand and help. Thanks

The IT landscape is this:
======================
We use a zimbra mail server on Debian Lenny. We performed a full server backup with tar. We don't use their own system of zimbra backups.

The incoviente is as follows:
==============================
A user has lost mail in a specified folder, as we all know zimbra mail saves mails dir in /opt/zimbra/store/ and within this directory is 0 which includes all user boxes and the incomming directory for mails processed.
Once I get the mailbox of the user in question, the tape recovered from the folder and I have all the mail for that user.
Recover some mail is not a problem because I can locate with grep. The first problem I have is when I need to restore an entire folder, making a localized grep mail directory contains more than one domain (the user saved in the user I have to retrieve mail from a single domain) but does not restore what I need.
The second problem I have is that I injectables all in the inbox and mixed with the mail containing the user in your inbox.
The command to use to inject the mail to retrieve:

zmlmtpinject -r user@dominio.com -s remitter@sudominio.com -d /path/where_is_the_tape_recovered_folder

What I need is:
================
1) differentiate the folder or the contents of the folder to restore, I don't know if there is something like a mailboxid for the mails, I can associate the mail with the directory that contains it.
2) inject mails in a folder that I can designate within the users mailbox.

Already thank you very much for the contribution they can make.
