Zimbra not Acessible

[samirpatba]

last weekend in my zimbra server problems presented in HD and now can not access the web interface, but I can still use some command via CLI.
Some problems:

Host server.mail.br
        antispam                Running
        antivirus               Running
        ldap                    Running
        logger                  Running
        mailbox                 Stopped
                zmmailboxdctl is not running.
        mta                     Running
        snmp                    Running
        spell                   Running
        stats                   Running

via SMTP I can send message normally, but I can't receive via POP/IMAP.
Using zmprov:

 zmprov
ERROR: zclient.IO_ERROR (invoke Connection refused, server: localhost) (cause: java.net.ConnectException Connection refused)

So, I installed a new zimbra server in a other machine and I import all accounts via LDAP.
Anyone can help me to import all messagens?

P.S.: Sorry for my english.
