    We've got a Zimbra server which is blacklisted by Symantec. We don't know why, so we want to hire someone who can look what the problem is (may be the server is not well protected or is sending spam).

    We have a problem with Zimbra 7 Server, running in a virtual machine Linux Ubuntu 8.04: the web interface is not working, but the service is up (zmconfigd is running). IMAP isn't working, too. We only need to access the Zimbra Server web interface or extract the e-mails database. It isn´t necessary to make Zimbra work again because our customer is already using Office365.
