◆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：[email protected] 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
