◆案例1◆ Postfix + Dovecot - 简易邮件服务器搭建
**************************************************************************************************

1.搭建DNS域名解析,解析邮件地址

a).安装bind

yum install -y bind

b).修改DNS配置文件 <只做一个正向邮件交换记录即可>

编辑配置文件,在相应的区域中修改以下标★语句
--------------------------------------------------------------------------------------------------------------
vim /etc/named.conf

10 options {
★ listen-on port 53 { any; };
★ listen-on-v6 port 53 { ::any; };
13 directory "/var/named";
14 dump-file "/var/named/data/cache_dump.db";
15 statistics-file "/var/named/data/named_stats.txt";
16 memstatistics-file "/var/named/data/named_mem_stats.txt";
★ allow-query { any; };
18

★ zone "lyshark.com." IN {
★ type master;
★ file "lyshark.com.zone";
★ };
59
60 #include "/etc/named.rfc1912.zones";
--------------------------------------------------------------------------------------------------------------

cp -a named.localhost lyshark.com.zone

c).编辑配置文件
--------------------------------------------------------------------------------------------------------------
vim /var/named/lyshark.con.zone

$TTL 1D
@ IN SOA dns.lyshark.com. rname.invalid. (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
NS dns.lyshark.com.
MX 3 mail.lyshark.com.
dns A 127.0.0.1
mail A 192.168.1.12
--------------------------------------------------------------------------------------------------------------

systemctl restart named

2.配置邮件服务器,邮件服务器是默认安装的直接配置即可

--------------------------------------------------------------------------------------------------------------
vim /etc/postfix/main.cf

myhostname = mail.lyshark.com #当前邮件服务器的主机名
mydomain = lyshark.com #指定邮件域

myorigin = $myhostname #设置允许发信的用户的邮件域
myorigin = $mydomain #例：lyshark@lyshark.com

inet_interfaces = all #侦听所有地址,取消注释
#inet_interfaces = localhost #注释掉

#mydestination = $myhostname, localhost.$mydomain, localhost #设置取出那些邮件,注释本行
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain #取消注释

home_mailbox = Maildir/ #设置邮件的位置

--------------------------------------------------------------------------------------------------------------

3.安装邮件检索代理,来查看接收的邮件

yum install -y dovecot dovecot-devel

systemctl restart dovecot

4.新建用户测试邮件是否正常

useradd -s /sbin/nologin lyshark
passwd lyshark

useradd -s /sbin/nologin alert
passwd alert
