实验环境fqdn: mail.apple.com
OS: Red Hat Enterprise Linux 5 update2
network: 192.169.200.1/24
/etc/resolve.conf
配置为
nameserver192.168.200.1
fqdn: mail.orange.com
OS: Red Hat Enterprise Linux 5 update2
network: 192.169.200.2/24
/etc/resolve.conf
配置为
nameserver192.168.200.1
fqdn: client1.apple.com
OS: Red Hat Enterprise Linux 5 update2
network: 192.169.200.3/24
/etc/resolve.conf
配置为
nameserver192.168.200.1
fqdn: client1.orange.com
OS: Red Hat Enterprise Linux 5 update2
network: 192.169.200.4/24
/etc/resolve.conf
配置为
nameserver192.168.200.1
目标在mail.apple.com
上搭建smtp
服务器
在mail.orange.com
上搭建smtp
服务器
client1.apple.com
通过mail.apple.com
向mail.orange.com
上的用户user1
发送信件
client1.orange.com
通过mail.orange.com
向mail.apple.com
上的用户user1
发送信件
流程概述
- 发信客户端把邮件交给发信服务器
- 发信服务器通过查看/etc/mail/local-host-names判断邮件是否属于本域，如果是，则扣押下来以备对应的用户查阅，如果不是，则向DNS查询该邮件所属区域的MX记录，向该邮件服务器传递邮件。这个时候其实是发信服务器在向目标发送邮件，而不是发信客户端直接向目标发送邮件。
实验步骤在mail.apple.com
上操作配置DNS
安装相关RPM
包[root@mailServer]# pwd
/misc/cd/Server
[root@mailServer]# rpm -ivh bind-9.3.4-6.P1.el5.i386.rpmbind-chroot-9.3.4-6.P1.el5.i386.rpmcaching-nameserver-9.3.4-6.P1.el5.i386.rpm

[root@mailServer]#
配置BIND
[root@mailServer]# cd /var/named/chroot/etc/
[root@mailetc]# mv named.caching-nameserver.conf named.conf
[root@mailetc]# mv named.rfc1912.zones named.zones
[root@mailetc]#
修改named.conf
和named.zones
配置配置如下
named.conf:
acl"mynet" { 192.168.200.0/24; };
options{
listen-onport 53 { 127.0.0.1; mynet; };
listen-on-v6port 53 { ::1; };
directory "/var/named";
dump-file "/var/named/data/cache_dump.db";
statistics-file"/var/named/data/named_stats.txt";
memstatistics-file"/var/named/data/named_mem_stats.txt";
query-source port 53;
query-source-v6port 53;
allow-query { localhost; mynet; };
};
logging{
channeldefault_debug {
file"data/named.run";
severitydynamic;
};
};
viewlocalhost_resolver {
match-clients { localhost; mynet; };
match-destinations{ localhost; };
recursionyes;
include"/etc/named.zones";
};
named.zones:
zone"." IN {
typehint;
file"named.ca";
};
zone"localdomain" IN {
typemaster;
file"localdomain.zone";
allow-update{ none; };
};
zone"apple.com" IN {
typemaster;
file"apple.com.zone";
allow-update{ none; };
};
zone"orange.com" IN {
typemaster;
file"orange.com.zone";
allow-update{ none; };
};
zone"200.168.192.in-addr.arpa" IN {
typemaster;
file"200.168.192.rzone";
allow-update{ none; };
};
zone"localhost" IN {
typemaster;
file"localhost.zone";
allow-update{ none; };
};
zone"0.0.127.in-addr.arpa" IN {
typemaster;
file"named.local";
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 {
typemaster;
file"named.ip6.local";
allow-update{ none; };
};
zone"255.in-addr.arpa" IN {
typemaster;
file"named.broadcast";
allow-update{ none; };
};
zone"0.in-addr.arpa" IN {
typemaster;
file"named.zero";
allow-update{ none; };
};
配置zone
