    Shouldn't but won't hurt to try, Postfix may store it's own cache of the domain. Try putting all the names on the same line:

    212.193.49.223 casper.mydomain.com capser mail.mydomain.com

    Restart postfix and try again.

    btw when the error is
    Jan 7 02:14:23 localhost postfix/smtp[23301]: AA87A57200B9: to=<[email protected]>, relay=none, delay=0.06, delays=0.04/0.01/0.01/0, dsn=5.4.4, status=bounced (Host or domain name not found. Name service error for name=mail.mydomain.com type=A: Host not found)

    does type A mean the dns record?

    the IP you get back is different than the one you specified in your hosts file. although that still doesn't solve the issue here.

    Can you post the output of:

    cat /etc/resolv.conf

    and is mydomain.com the real domain here? is it public?
     
  7. tyliong

    tyliong New Member

    of course not mydomain isn't the real domain of the server nor are those ip numbers. the domain name is something else but its public, server currently is in deployment and security is a bit laxed at the moment.

    btw the ip numbers are actually matching i just forgot to put it right

    the ip number in the resolv is real though

    cat /etc/resolv.conf
    search localdomain

    nameserver 203.120.90.40
     
  8. volksman

    Yes it is referring to an A record in DNS. which is weird cause ping finds it no problems. Might be a partially busted zone file, without knowing the real zone it's impossible to test.

    Have you made any modifications to /etc/nsswitch.conf?

    Try 'dig +short @203.120.90.40 mail.mydomain.com'. That's doing a lookup off the same DNS server you configured the server to use.

    PM me the domain if you want me to dig deeper on the DNS issue.

    no modifications to /etc/nsswitch.conf

    /var/named/chroot/var/named/foodspree.com.db

    i changed dns here to
    mydomain.com. IN NS ns1.mydomain.com.
    ;mydomain.com. IN NS ns2.mydomain.com.
    IN MX 20 smtp.mydomain.com.
    IN MX 10 mail.mydomain.com.
    ns1 IN A 213.193.49.223 ;primary name server
    ;ns2 IN A 213.193.49.223 ;secondary name server
    casper IN A 213.193.49.223
    ;serverB IN A 192.168.1.2
    smtp IN A 213.193.49.223 ;mail server
    mail IN A 213.193.49.223
    www IN CNAME casper ;web server
    ftp IN CNAME casper ;ftp server

    dig +short @203.120.90.40 mail.mydomain.com

    does not give anything

    what do u need for the real zone file?

    tyliong New Member
