What do you think would happen if you required authentication on Port 25 (i.e. the SMTP port)? The quick answer is you wouldn't be able to receive any email.

I am new to Zimbra, i have successfully setup Zimbra zcs-8.6.0_GA_1153.RHEL7_64.20141215151110 on centos 7. Seriously, you've installed that old version?

Is this ZCS server on a LAN? I believe this error happens when a private-key is associated with a wrong public-key or you have no public-key in your dns. If it's on a LAN then I'd check your DNS records. Does this happen with mail from all users or just one?
