I install Zimbra 6 under Debian 5. All services started, statistics also OK. I setting up NOTHING any more.
Internal mail in my zimbra-mail-domain would be delivering between zimbra-mail-domain-users? Or I've to additional setup the Zimbra? :confused:
I think this would be worked. Before starting, you must ensure the DNS is correct and add some users.
In this case, IMHO, DNS-records unimportant, because we've working with INTERNAL mail, haven't it? Or I'm wrong?
I still suggest you check the DNS record, because ZCS is very dependent on that.
