ear All,

I setup an DNS Bind9 with 3 domains and host mail zimbra for 3 domain on it.

Hostname: zmail.micro.net

Three domain

A.COM
B.COM
C.COM

db.a.com

Code:
$ORIGIN .
$TTL 604800
a.com.      IN      SOA     zmail.micro.net.        admin.micro.net$
                        070725  ;
                        604800  ;
                        86400   ;
                        2419200 ;
                        604800 )
;
        IN      NS      zmail.micro.net.
        IN      MX      10      mail.a.com.
zmail.micro.net IN      A       192.168.0.1
$ORIGIN a.com.


Code:
$ORIGIN .
$TTL 604800
b.com.      IN      SOA     zmail.micro.net.        admin.micro.net$
                        070725  ;
                        604800  ;
                        86400   ;
                        2419200 ;
                        604800 )
;
        IN      NS      zmail.micro.net.
        IN      MX      10      mail.b.com.
zmail.micro.net IN      A       192.168.0.1
$ORIGIN b.com.



Code:
$ORIGIN .
$TTL 604800
c.com.      IN      SOA     zmail.micro.net.        admin.micro.net$
                        070725  ;
                        604800  ;
                        86400   ;
                        2419200 ;
                        604800 )
;
        IN      NS      zmail.micro.net.
        IN      MX      10      mail.c.com.
zmail.micro.net IN      A       192.168.0.1
$ORIGIN c.com.
I can nslookup to zmail.micro.com, dig mx record of 3 domain.
But when I send mail it said host or domain name not found. name service error name=zmail.micro.net type=a: host not found try again

I known that is Bind9 issue. What happen with my DNS Server???
