一个有关DNS与SENDMAIL的难题。
局域网内有两台电脑，分别装Linux7.2，sendmail。
其中，PC1做DNS服务器，IP是：192.168.10.1，域名是：test.com。
PC2的IP是：192.168.10.2，域名是：domain.com，PC2的DNS指向PC1。
配置PC1的DNS可以正常解析test.com和domain.com。
配置两台机器的sendmail可以正常向外（如：新浪等）发邮件，sendmail.cf由/etc/mail/sendmail.mc生成，可是在test.com和domain.com之间互相发邮件是却碰到了同样的错误。
OUTLOOK中错误如下：
The original message was received at Sun, 23 Mar 2003 20:35:20 -0800
from [192.168.10.1]
----- The following addresses had permanent fatal errors -----
(reason: 553 5.3.5 system config error)
----- Transcript of session follows -----
553 5.3.5 mail.test.com. config error: mail loops back to me (MX problem?)
554 5.3.5 Local configuration error
下面是我的DNS配置：
[root@server named]# less /etc/named.conf显示：
zone "test.com" {
type master;
file "test.com.zone";
};
zone "domain.com" {
type master;
file "domain.com.zone";
};
[root@server named]# less test.com.zone显示：
$TTL 86400
@ IN SOA @ root.localhost (
8 ; serial
28800 ; refresh
7200 ; retry
604800 ; expire
86400 ; ttl
)
@ IN NS server
@ IN MX 10 mail
server IN A 192.168.10.2
mail IN A 192.168.10.2
[root@server named]# less domain.com.zone显示如下：
$TTL 86400
@ IN SOA @ root.localhost (
8 ; serial
28800 ; refresh
7200 ; retry
604800 ; expire
86400 ; ttl
)
@ IN NS server
@ IN MX 10 mail
server IN A 192.168.10.1
mail IN A 192.168.10.1
日志文件的信息如下root@server named]# tail ../log/maillog ：
