Zimbra on Ubuntu, please help me with 2 problem
Hi, i have installed Zimbra on Ubuntu thanks to Howto :)
Now i have 2 problems:

1 - If i have understand right Zimbra don't request mta/smtp user authentication when you send emails via smtp with a client in local network with Zimbra.
es. zimbra server stmp ip
email client ip
Is this right?
How can i force mta/stmp to authenticate a client in local network? I have seen that if you use a fake user with a fake domain you can however send emails... why?

2 - Zimbra use external dns servers also for delivery local mail? I don't have a dns server, for now, to add an A and a MX record for my test domain. There is a mode to tell zimbra to delivery local mail without a record mx?

1) run the command:

postconf -e 'mynetworks ='

and then restart postfix to deny relaying for clients in your network without authentication.

2) Add a line like this to the /etc/hosts file on your server to override external DNS settings:

Hi, Zimbra definitely needs a DNS Server as it requires an A- and an MX-record. Since you do not have a DNS domain yet (I presume), I would suggest installing a local DNS server (e.g. BIND) and then configure your own domain there.

After installing and configuring Bind (setup forwarders to your ISP's dns!), just edit the /etc/resolv.conf file and point it to or your server's IP address.

Also, remove the lines in your /etc/hosts as they will only cause confusion and other errors later on !
