question about CNAME

[Ben Bridges]

What is not working?  Are you not getting the CNAME record for email.test.com?  Are you not getting the A record for email.tzqian.com?  Are both zones on the same dns server, or is each zone on a separate server?  Which server are you querying, and from what device are you issuing the query?

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:
ZONE 1:
$ORIGIN .
$TTL 86400      ; 1 day
test.com                IN SOA  test.com. www.test.com. (
                                19970229 ; serial
                                10         ; refresh (10 seconds)
                                10         ; retry (10 seconds)
                                30         ; expire (30 seconds)
                                30         ; minimum (30 seconds)
                                )
                        NS      localhost.
                        A       10.0.0.13
$ORIGIN test.com.
1                       PTR     localhost.
email           CNAME  email.tzqian.com.

ZONE 2:

$ORIGIN .
$TTL 86400      ; 1 day
tzqian.com              IN SOA  tzqian.com. support.tzqian.com. (
                                1997022706 ; serial
                                10         ; refresh (10 seconds)
                                10         ; retry (10 seconds)
                                30         ; expire (30 seconds)
                                30         ; minimum (30 seconds)
                                )
                        NS      localhost.
                        A       10.0.0.13
$ORIGIN tzqian.com.
1                       PTR     localhost.

	Can you just post your zone file, copy and paste, and do not change any data in it, use real IP's.  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.
	
	Here is an example:
	
	Server #1
	email.server    IN      A      192.168.1.100
	
	Server #2
	email           IN      CNAME  email.server.yourzone.com.
	
	I am still not sure I understand your issues, you need to show us both zones, and tell us each zones host name.

		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
		to add an A record as follows (zone.com):
		email.xx  A       12.2.23.4
		and in another DNS server I add an CNAME record as follows:
		email          CNAME      email.xx.zone.com.
		but it dosen't work.who can tell me why ?
