zimbra store process

hello, I should fix a zimbra server with incosistent mysql data. After a disk failures-restore i've a lot of messages without the related record in mail_item as shown by the command:
./zmblobchk -m 24 start
...
Mailbox 24, volume 3, /dati/zimbra/store/0/24/msg/33/136036-181524.msg: unexpected blob. File size is 1521.
....
To insert the missing records in the table mail_item, i have to get how calculate the content.
I figure out the rule used to name the message thanks to the wiki page about the mailbox database structure, but i don't know how to set the fields blob_digest, meta_data, parent_id, mod_metadata, index_id.
Maybe i could leave null the index_id and force zimbra to reindex.
It seems zimbra use the chain postfix trasport map - openldap - jetty - java code:

#./postfix/sbin/postconf transport_maps
transport_maps = proxy:ldap:/opt/zimbra/conf/ldap-transport.cf
#/opt/zimbra/openldap/bin/ldapsearch -Hldap://mioserver.it -x -LLL -D "uid=zmpostfix,cn=appaccts,cn=zimbra" -w XXXXXXXX '(zimbraMailTransport=*)'
...
zimbraMailTransport: lmtp:mioserver.it:7025
...

The xml file /opt/zimbra/mailboxd/etc/jetty.xml seems to configure the contexts-handlers for the zimbra web applications, the file /opt/zimbra/mailboxd/etc/jetty-setuid.xml it seems open various socket taking parameters by the file /opt/zimbra/mailboxd/etc/jetty.properties.
It calls the method openport of the com.zimbra.common.handlers.PrivilegedHandler, with the hash of proprieties read in the jetty proprieties.file as argument. This class imports ./ZimbraCommon/src/java/com/zimbra/common/util/NetUtil.java to instantiate the socket object.
I can't found the accept call on the socket object, maybe I miss some steps, I'm not a java programmer.

Could anyone help me to understand the stack call used to store the message?
Is there an apposite procedure to create the mysql records from the files?
Should I care something before to insert manually the missing records?
