Hello
I just installed opensource Zimbra 7.2 on CentOS. This server is supposed to be a test Zimbra server
mta seems to be green, but I cannot send an e-mail from one account to another on the same server.
I googled: it is probably a DNS configuration issue.
I'm a total beginner in these issues as well as Linux, so I can't understand what am I doing wrong
These are my config files:
named.conf:
Code:
options {
directory "/var/named";
dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";
forwarders {
192.168.20.1;
};
};
include "/etc/rndc.key";
zone "zimbratest.co.jp" {
type master;
file "db.mail.systec.local";
};
resolv.conf

Code:
search zimbratest.co.jp
nameserver 192.168.20.51
db.mail.systec.local
Code:
$TTL 460000
@  IN  SOA  zimbratest.co.jp. adminaccount.zimbratest.co.jp (
10118  ; Serial
43200  ; Refresh
3600  ;Retry
3600000  ; Expire
2592000) ; Minimum
   IN  NS zimbra;zimbra.systec.local
zimbra   IN  A 192.168.20.51
   IN   MX  10 zimbra
mail IN A 192.168.20.51
IN MX 10 mail                             
ns IN CNAME zimbra
/etc/hosts
Code:
127.0.0.1   localhost.localdomain localhost
:1         localhost6.localdomain6 localhost
192.168.20.51 zimbra.zimbratest.co.jp zimbra
192.168.20.51 mail.zimbratest.co.jp mail
What's wrong with the configuration?
