Welcome to the forums

Why not just put the appropriate A records into the BIND install on server A and point server B /etc/resolv.conf at server A ?

[vikjava]

thank uxbod!

bind install on the server A (MTA) or bind install on server B(Ldap,mailbox) ???
I install bind on server B (LDAP,maibox),is this wrong?

Why not just put the appropriate A records into the BIND install on server A and point server B /etc/resolv.conf at server A ?-->> can you explain more clearly ?

thanks!

[uxbod]

You can install BIND on Server B just fine; either will do. Example :-

Domain - example.com
Server A - 10.0.0.10 - a.example.com
Server B - 10.0.0.20 - b.example.com

BIND installed on Server B and with the following records :-

IN MX 10 a.example.com.
a IN A 10.0.0.10
b IN A 10.0.0.20

/etc/resolv.conf on Server A and B would be :-

search example.com
server 10.0.0.20

[vikjava]

hi uxbod
My domain - vietkt.com
Server A (MTA) - 10.0.0.1 -mta.vietkt.com
Server B(mailbox,ldap) - 10.0.0.2 -mail.vietkt.com
Bind installed on server B and with the following records:

vietkt.com. IN SOA mail.vietkt.com. admin.mail.vietkt.com. (
070725 ;serial
604800 ;refesh
86400 ;retry
2419200;expire
604800);negative cache tll
;
vietkt.com. IN NS mail.vietkt.com.
vietkt.com. IN MX 10 mail.vietkt.com.
mail IN A 10.0.0.2
mta IN A 10.0.0.1

/etc/resolv.conf on Server A and B :
search vietkt.com
nameserver 10.0.0.2

When i send a mail,the error :

A network service error has occurred.

Any error messages in /var/log/zimbra.log as all your server names are resolving okay ?
