thanks for your response.I do this test between two intranet machine and each of them has a local IP.10.0.0.13,additionally the both domain are in the same DNS SERVER 10.0.0.13 ,the zone file as follows:<br>ZONE 1:<br>$ORIGIN .<br>
$TTL 86400 ; 1 day<br><a href="http://test.com">test.com</a> IN SOA <a href="http://test.com">test.com</a>. <a href="http://www.test.com">www.test.com</a>. (<br> 19970229 ; serial<br>
10 ; refresh (10 seconds)<br> 10 ; retry (10 seconds)<br> 30 ; expire (30 seconds)<br> 30 ; minimum (30 seconds)<br>
)<br> NS localhost.<br> A 10.0.0.13<br>$ORIGIN <a href="http://test.com">test.com</a>.<br>1 PTR localhost.<br>
email CNAME <a href="http://email.tzqian.com">email.tzqian.com</a>.<br><br>ZONE 2:<br><br>$ORIGIN .<br>$TTL 86400 ; 1 day<br><a href="http://tzqian.com">tzqian.com</a> IN SOA <a href="http://tzqian.com">tzqian.com</a>. <a href="http://support.tzqian.com">support.tzqian.com</a>. (<br>
1997022706 ; serial<br> 10 ; refresh (10 seconds)<br> 10 ; retry (10 seconds)<br> 30 ; expire (30 seconds)<br>
30 ; minimum (30 seconds)<br> )<br> NS localhost.<br> A 10.0.0.13<br>$ORIGIN <a href="http://tzqian.com">tzqian.com</a>.<br>

Or at least obfuscate them in a way that makes sense to the rest of us. There really is not a lot of sense in obfuscating a public data store anyway.<br>
<br>
Here is an example:<br>
<br>
Server #1<br>
email.server IN A 192.168.1.100<br>
<br>
Server #2<br>
email IN CNAME <a href="http://email.server.yourzone.com" target="_blank">email.server.yourzone.com</a>.<br>
<br>
I am still not sure I understand your issues, you need to show us both zones, and tell us each zones host name.<div class="im"><br>

I think I should explain the question more clearly,I am wondering how cname reflect the address,so I do a test in my server<br>
to add an A record as follows (<a href="http://zone.com" target="_blank">zone.com</a>):<br>
email.xx A 12.2.23.4<br>
and in another DNS server I add an CNAME record as follows:<br>
email CNAME <a href="http://email.xx.zone.com" target="_blank">email.xx.zone.com</a>.<br>
but it dosen't work.who can tell me why ?<br>
