    Exclamation LDAP won't start due to changes in DNS records

    Hi folks, I rewrite this post because evidently the forums are not as safe as they promises to be, I edited my-first-post title in advanced mode and the system left the post with an empty content...
    Anyway, it doesn't mother, I am going to explain the problem again xD.

    We have a problem with the Zimbra Service either when we try to start it manually or when it auto-loads itself at the boot time due (apparently) to an LDAP problem!
    Previously, we had changed DNS Records such as MX and others in order to change the server to a new one, so, when we got back to the old server, the described problem had appeared.

    Now, the question is, How can I do to start the Zimbra service without it to check the DNS or whatever, just to perform a backup and move data to the new server??
    Can I keep MDA without MTA? And take the emails back via IMAP for example?

    I paste here some outputs I get...

    The checksum error is a red herring. Likely it cannot bind to the hostname/IP combination specified for your server.
