详细讲解 搭建Linux邮件网关与邮件系统

环境：vmware下RedHat EL3 x 3

ServerA ip:192.168.0.231 邮件网关server DNS server

ServerB ip:192.168.0.232 邮件系统server

ServerC ip:192.168.0.233 邮件系统server

实验域：

ServerB: wllhc.org ServerC: thiz.net

实验目的：

ServerB和ServerC下的邮件用户用自己的邮件服务器互相收发邮件并通过网关发送，通过ServerA解析对方IP

一、在ServerA上安装邮件网关，配置邮件服务器的DNS

1.安装网关

#wget http://192.168.0.11/pkg/mail_gw/1026/gw_3.6_050430.tar.gz /opt

#tar -zxvf gw_3.6_050430.tar.gz

#cd gw_3.6

#./install.sh

搭建邮件网关与邮件系统

环境：vmware下RedHat EL3 x 3

ServerA ip:192.168.0.231 邮件网关server DNS server

ServerB ip:192.168.0.232 邮件系统server

ServerC ip:192.168.0.233 邮件系统server

实验域：

ServerB: wllhc.org ServerC: thiz.net

实验目的：

ServerB和ServerC下的邮件用户用自己的邮件服务器互相收发邮件并通过网关发送，通过ServerA解析对方IP

1.安装网关

#wget http://192.168.0.11/pkg/mail_gw/1026/gw_3.6_050430.tar.gz /opt

#tar -zxvf gw_3.6_050430.tar.gz

#cd gw_3.6

#./install.sh

2.配置DNS

#vi /etc/named.conf

options {

directory "/var/named";

};

zone "." IN {

type hint;

file "named.root";

};

zone "localhost" IN {

type master;

file "localhost.zone";

allow-update { none; };

};

zone "0.0.127.in-addr.arpa" IN {

type master;

file "named.local";

allow-update { none; };

};

zone "wllhc.org" IN {

type master;

file "wllhc.zone";

allow-update { none; };

};

zone "0.168.192.in-addr.arpa" IN {

type master;

file "0.168.192";

allow-update { none; };

};

zone "thiz.net" IN {

type master;

file "thiz.zone";

allow-update { none; };

};

controls {

inet 127.0.0.1 port 953

allow { 127.0.0.1; } keys { "rndc-key"; };

};

3,#vi /var/named/wllhc.zone

$TTL 86400

@ IN SOA wllhc.org. root.wllhc.org.(

42 ;serial(d. adams)

3H ;refresh

15M ;retry

1W ;expiry

1D) ;minimum

IN NS wllhc.org.

IN MX 1 mail.wllhc.org.

www IN A 192.168.0.232

mail IN A 192.168.0.232

@ IN A 192.168.0.232

4,#vi /var/named/thiz.zone

$TTL 86400

@ IN SOA thiz.net. root.thiz.net.(

42 ;serial(d. adams)

3H ;refresh

15M ;retry

1W ;expiry

1D) ;minimum

IN NS thiz.net.

IN MX 1 mail.thiz.net.

www IN A 192.168.0.233

mail IN A 192.168.0.233

@ IN A 192.168.0.233

二、在ServerB,ServerC上安装邮件系统并填加相应的域

1.首先要指定ServerB,ServerC的gw和dns为ServerA

ServerB #vi /etc/resolv.conf

nameserver 192.168.0.231

ServerB #vi /etc/sysconfig

NETWORKING=yes

HOSTNAME=localhost.localdomain

GATEWAY=192.168.0.231

ServerC #vi /etc/resolv.conf

nameserver 192.168.0.231

ServerC #vi /etc/sysconfig

NETWORKING=yes

HOSTNAME=localhost.localdomain

GATEWAY=192.168.0.231

2.安装邮件系统

ServerB #wget http://192.168.0.11/pkg/email/410/linux_binary_installer-4.1.0.tar.gz /opt

ServerB #tar -zxvf /opt/linux_binary_installer-4.1.0.tar.gz

ServerB #cd /opt/linux_binary

ServerB #./install.sh

ServerB #mozilla mail.wllhc.org/admin/　#用管理员身份在此邮件系统中添加wllhc.org这个域

ServerC #wget http://192.168.0.11/pkg/email/410/linux_binary_installer-4.1.0.tar.gz /opt

ServerC #tar -zxvf /opt/linux_binary_installer-4.1.0.tar.gz

ServerC #cd /opt/linux_binary

ServerC #./install.sh

Install Finished

ServerC #mozilla mail.thiz.net/admin/　#用管理员身份在此邮件系统中添加thiz.net这个域。

三、将windows环境的网关和DNS指向192.168.0.231,用Foxmail使用默认帐户support。邮件地址分别为support@wllhc.org和support@thiz.net，互相给对方发信测试成功。

PS:注意测试时记得停掉ServerA和ServerB的防火墙，如果之前还运行着其他的MTA如sendmail记得停掉，不然会出现如“端口被占用”类似的错误。

/var/eyou/etc/eyou_smtpd_config

在/var/eyou/openldap/etc/openldap/slapd.conf文件大概在32行,有一个字段: suffix "o=eyou.com"，

将eyou.com改成和/var/eyou/etc/eyou_smptd_config文件中sys_dn字段o的值一样,即nttc.edu.cn。

在34行,有一个字段:rootdn "cn=eYouAdmin,o=eyou.com" 也将o=eyou.com改成o=nttc.edu.cn
