dual NIC and send emails to a second zimbra server

Postby ciprianl » Wed Mar 23, 2011 2:04 pm

Hello,

I have this situation:

server 1 : ZMAIL.domain.com with 2 nics, one for Internet and one for LAN

server 2 : BMAIL.domain.local connected in LAN
The second server has the role to keep back-up emails for every account I made in server 1. I doubled all account from server 1 and I forwarded every account to its correspondent in server 2.
The problem is that emails are not delivered because DNS server (from ISP) does not know my domain.local (that's normal). Even after I set bmail.domain.local in etc/hosts with its private IP didn't solve anything because postfix checks mx record from DNS not from hosts.
I do have another local DNS in LAN (my domain controller 2008 R2) but Zimbra checks only its first DNS (from ISP).
Can somebody help me? How can I solve this?

have you tried adding the 2008 server as r2 as another dns server on the zimbra box? like as a 3rd?

The problem is that postfix is checking only the first dns server. It will pass to the next server only if the first is down, which is not the case. For the moment I changed the first dns to my 2008 R2 server. It's working now but it is not the "correct " solution.
