[help] Installing ZCS in single shared Public IP

[si_faisal]

Helo everyone, im reza
Straight to the point, i need help here

I've installed ZCS as mail server in DMZ,
this is my network topology :



its working when i recieved / send mail from internal user
but when i tried to internet (ie. gmail.com) the mailer daemon reply error messages that notice sender ip address is not same with MX address

i run zimbra web in port 81, and then activate virtual host mail.te-unsoed.web.id point to 10.10.33.1:81

the question is,
1. how to config zimbra and dns server for fully working internet mail server?
2. do i have to setup such as mail relay in the router (A)? how to config zimbra with that?
3. do i need to setup new DNS master zone for my DMZ (ie. mail.te-unsoed.dmz)?

please give me some hand, i'm a newbie in mail server things

Thanks in advance

The Zimbra server needs to be able to resolve the MX record to the internal IP address of the server. You can either use your current DNS server or install a copy of BIND on the Zimbra server as shown in the wiki article. You can test the resolution with the following:

host `hostname`
dig yourdomain.com any
dig yourdomain.com mx

If you run them on the Zimbra server they should return the IP address of that server for the A & MX records and the host command should return the hostname and IP address of the server.
