error Resolving MX record

**debasmita** · 10-25-2009, 11:00 PM

hi ..........
this is debasmita and am installing zcs 6.0 on linux platform.

dns server and Zimbra are installed in the same system itself with IP 192.168.10.2 and FQDN mailadmin.hcl.org.

configuration of /etc/hosts

Code:

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1       localhost.localdomain   localhost
192.168.10.2     mailadmin.hcl.org       mailadmin

Code:

#vi /etc/resolve.conf
nameserver 192.168.10.2
domain hcl.org
search hcl.org

I have set up the same system as DNS server as well as Zimbra admin server....
configuration of /etc/named.conf

Code:

zone "hcl.org" IN {
        type master;
        file "orgforward.zone";
        allow-update { none; };
};

zone "10.168.192.in-addr.arpa" IN {
        type master;
        file "orgreverse.zone";
        allow-update { none; };
};

configuration of forward and reverse zone files:

Code:

#cd /var/named/chroot/var/named
# vi orgforward.zone
$TTL    86400
@               IN SOA  mailadmin.hcl.org root.mailadmin.hcl.org (
                                        42              ; serial (d. adams)
                                        3H              ; refresh
                                        15M             ; retry
                                        1W              ; expiry
                                        1D )            ; minimum
                        IN              NS      mailadmin.hcl.org.
                        IN              MX  10  mailadmin.hcl.org.
mailadmin               IN A            192.168.10.2

# vi orgreverse.zone
$TTL    86400
@       IN      SOA     mailadmin.hcl.org. root.mailadmin.hcl.org.  (
                                      1997022700 ; Serial
                                      28800      ; Refresh
                                      14400      ; Retry
                                      3600000    ; Expire
                                      86400 )    ; Minimum
              IN      NS      mailadmin.hcl.org.

2             IN      PTR     mailadmin.hcl.org.

Code:

# service named restart

now the comaands

Code:

dig hcl.org any
dig hcl.org mx

are also giving the desired o/p.

but while installing zcs 6.0 it is giving the error as
ERROR RESOLVING MX RECORD FOR DNS mailadmin.hcl.org

its getting installed and mails are getting delivered in lan within two different domains but its not getting delivered to gmail or yahoomail. Moreover while am checking the MX record from within the Zimbra Admin console ... its showing
Failed to retrieve MX records for domain mailadmin.hcl.org.

Please provide a solution.

THANKS in Advance

debasmita you have setup MX records for hcl.org.... not mailadmin.hcl.org which it looks like is what you have configured as the domain in Zimbra. You might want to try setting up your zimbra server to have hcl.org as the domain (unless you specifically want mailadmin.hcl.org to be the domain in which case your DNS is totally wrong...
