Dear,
I have two domain in local network (192.168.10.0/24). Please help me to configure for sending/receiving mail two domain each other.

1st domain:
Name: encverdi.com
Domain Controller/Exchange/DNS was installed in Windows 2008 (Trial version)
Host Redord: dcmail.encverdi.com
IP: 192.168.10.41
Webmail: https://192.168.10.41/owa/

2nd domain:
Name: enclocal.com
DNS/Zimbra was installed in CentOS 6.5
Host Record: dnsrv.enclocal.com
Wemail: https://192.168.10.42/

In ecach domain, every things work well. sending/receive has already worked well.
But now, I try to configure to send/receive mail two domain encverdi.com and enclocal.com each other.
I configured in DNS server of encverdi.com (1st domain) to resolve enclocal.com (2nd domain). It worked. From encverdi.com server, I can nslookup enclocal.com successfully.
But from enclocal.com, it is not successful.

This is file /var/named/forward.enclocal of enclocal.com DNS server:
------------
$TTL 86400
@ IN SOA dnsrv.enclocal.com. root.enclocal.com. (
2011071001 ;Serial
