Re: Zimbra and iptables problem

This is not a zimbra problem. Sounds like you're blocking dns requests based on the limited logs you provided.

Re: Invalid login attempts lockout user access

I'd suggest you start banning ips that are doing it. You could use something like fail2ban. There's various posts in the forum that discuss this.

Re: live_syncd zmhsm connection refused

Ldap is backed up via rsync and ssh. Is ssh running on port 22? What's in mailbox.log?

Re: Zimbra Collaboration 8.8.6 Hotfix now available

That's a known issue if the way we patch. It's not a problem with the software and when you later upgrade to 8.8.7 or later it'll go back to showing foss.

Re: Problems POP3S after upgrade to 8.8.6 ... proxy?

Sounds like they typed something wrong for the pop3 credentials. %20 is the @ symbol. It could be the client they're using is doing during dumb but it seems like clients should know how to handle that properly. Wow, you brought my attention possibly to the culpit of the problem. %20 is not @ symbol...
