See /opt/zimbra/postfix/conf/main.cf, and look for "trust", as it describes the behavior that you are seeing.

I've just installed Zimbra CS on a vm for testing purpose. ZCS is on a private lan, natted to Internet with port 25 forwarded from the firewall to zimbra private ip.
I've tested smtp authentication with
Email Server Test - Online SMTP diagnostics tool. Seems like zimbra accepts rcpt to without asking for authentication.
What's wrong with this ? Is a nat problem ? Or is that service not reliable ?
Thanks for your help.
