Recently I setup DNS server on my domain by using LINUX.
This machine also has FTP, MAIL service.
This machine's host name is 'DNS'.
The following is my Zone.db file
----------------------------------------------------------------------------
--------------
@ IN SOA dns.my-domain-name.com. hostmaster.my-domain-name.com. (
199910161 ; Serial
28800 ; Refresh
7200 ; Retry
604800 ; Expire
86400 ) ; Minimum
@ NS dns.my-domain-name.com.
@ NS dns2.my-domain-name.com.
@ MX 10 mail.my-domain-name.com.
localhost A 127.0.0.1
dns A dns-ip-address
dns2 A dns2-ip-address
www A web-server-ip-address
mail CNAME dns
ftp CNAME dns
----------------------------------------------------------------------------
-----------
My problem is that mail exchange.
I can send and receive a mail with account at dns.my-domain-name.com
But when I send a mail, receiver receives account at dns.my-domain-name.com
and when somebody send mail without hostname (like
account at my-domain-name.com),
he receives returned mail as follows :
----------------------------------------------------------------------------
-------------
----- The following addresses had permanent fatal errors -----
<account at my-domain-name.com>
----- Transcript of session follows -----
... while talking to mail.domain-name.com.:
>>> RCPT To:<account at my-domain-name.com>
<<< 551 <account at my-domain-name.com>... we do not relay
550 <account at my-domain-name.com>... User unknown
----------------------------------------------------------------------------

What is my problem?
How can I send e-mail without hostname?
Thanks in advance
