postfix and mta error

[phoenix]

alright i have fix that already , do you want me to post the digs?
my postfix still not working.

Yes, please. According to the dig information you've posted above, you have no MX record for the domain alghurair.com.

[mahmoud]

this is the digs with new modification i made , i make an error in the previous installation , mail.alghurair.com is my real mail server so when digged it is getting the dns of that server however here is the new modifacations .

[root@test /]# dig alghurair.com mx

now here is the strange thing:

[root@test /]# host `hostname`
Host test.alghurair.com not found: 3(NXDOMAIN)

i have done appendings in named-conf file and i did the file db.test.alghurair.com according to the guidance in the wiki's but still no luck

You have not created A or MX records for your domain, they are not showing in your output. Search the forums for 'DNS in a Nutshell' and follow the instruction in that thread for configuring your DNS.

The output would also indicate that your /etc/hosts file is incorrect, please post the output of:

cat /etc/hosts

[mahmoud]

[root@test /]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
192.168.21.75 test.alghurair.com test

can you help me with that dns thing i read the wiki and split dns millions of times i am so lost if you have something like doing that from the bash command it will be much easier to me.

the main issue is that iam new to dns and mx records and i can see it very complex thing to me to understand as the examples are very tricky also .

[phoenix]

The requirements for DNS in Zimbra are fairly simple, post the output of your configuration files.

[phoenix]

You should also post the output of resolv.conf from the Zimbra server.

[mahmoud]

Also i have one question relating to the zimbra setup:
iam getting a port conflict during installing mta which uses port 25 , i know that port 25 is used by ssh mean while i cant kill that service because zimbra already uses it ,

the question is : is there is no way to install mta in different port? this is the main problem iam facing here.

i have read in the forums and the wiki's about that problems and frankly speaking i dont know how it has been solved because first during the installation zimbra dont allow the user to choose the ports , second most users faces that problems was having service sendmail ON so when they kill the service everything run correctly , i hope iam that lucky that my problem is just a running service need to be down:-)

Regards

[phoenix]

Port 25 is the SMTP mail port not ssh, check if postfix (or sendmail) is running and then stop it and disable it from starting.

[root@test /]# cat /etc/resolv.conf
; generated by /sbin/dhclient-script
nameserver 192.168.20.15

That is named-conf:

[root@test /]# cat /etc/named.conf
//

//

options {

dump-file "/var/named/data/cache_dump.db";

forwarders { 192.168.21.75 ; };
};
include "/etc/rndc.key";
// We are the master server for test.alghurair.com
zone "test.alghurair.com" {
type master;
file "db.test.alghurair.com";
};

//

};

zone "." IN {
type hint;
file "named.ca";
};

zone "localdomain" IN {
type master;
file "localdomain.zone";
allow-update { none; };
};

zone "localhost" IN {
type master;
file "localhost.zone";
allow-update { none; };
};

zone "0.0.127.in-addr.arpa" IN {
type master;

allow-update { none; };
};

zone "0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0 .0.0.0.0.0.0.ip6.arpa" IN {

allow-update { none; };
};

zone "255.in-addr.arpa" IN {
type master;
file "named.broadcast";
allow-update { none; };
};

zone "0.in-addr.arpa" IN {
type master;
file "named.zero";
allow-update { none; };
};

that is my db.test.alghurair.com:

[root@test /]# cat var/named/db.test.alghurair.com
;

IN NS <internal address of server>
IN A <internal address of server>
IN MX 10 test.alghurair.com

and again thanks for your help

[uxbod]

Okay, so what is the short name of your server ? test.alghurair.com is your domain name and you have pointed the MX record too test.alghurair.com. It should be pointing to something like mail.test.alghurair.com where the FQDN of your ZCS server would be mail.test.alghurair.com.
