    Didn't get a backup over to the other machine.

    But I'm ready with two backups on the box.

    And just to underline jholder's post from earlier, a strong recommendation to tighten up firewall security between your server and the big bad world. You should really close up all ports not absolutely required by your users--at a minimum of course you need to let in 25 (SMTP) and 443 (https for webmail); if you have POP users you'll need either 110 (clear-text) or 995 (secure); if you do IMAP from outside you'll need 143 (clear-text) or 993 (secure). SSH (22) and Zimbra Admin (7071) should really be restricted to authenticated users on a VPN or within your LAN only, for the very reason you have just experienced.

    I've also thought for a while that we might consider having the Zimbra name removed from the login screen (pre-authentication) just to give snoopers less of an idea what they need to research if they want to crack a server they have discovered. . .thoughts, guys?
