1. Did you add MX record to your DNS server ? you should.

No i didn't.First of all ,i didn,t configure this as a DNS server,only as a DNS client.Also the /etc/mail/sendmail.cf is shown you for your reference.

2. Type this command:

# domainname

3. Type this also:

# cat /etc/resolv.conf
nameserver <ip address >

4. type

# nslookup Jaya
Server: < ip address >
Address: < ip address >
** server can't find Jaya: NXDOMAIN

# ping Jaya
Jaya is alive

RESOLV.CONF(5)							File Formats Manual						    RESOLV.CONF(5)

NAME

       resolv.conf - Domain Name System resolver configuration

SYNOPSIS

       /etc/resolv.conf

DESCRIPTION

       The  /etc/resolv.conf  is used to configure how the host will use the Domain Name System to resolve hostnames to IP addresses.  It may con-
       tain these two lines:

	      nameserver     IP-address
	      domain	     domain-name

       The nameserver entry tells the IP address of the host to use for DNS queries.  If it is set to 127.0.0.1 (which is the  default)  then  the
       local  name  daemon is used that may use the /etc/hosts database to translate host names.  You normally only need a nameserver entry if the
       name server is at the other side of a router.  The default nonamed name server can't look beyond the local network.

       The domain entry tells the default domain to use for unqualified hostnames.  This entry is usually not given in which case  the	domain	of
       the local host is used.

       The long version of this story can be found in resolver(5).

FILES

       /etc/resolv.conf    DNS resolver configuration file.
