Sendmail 配置实例介绍(1)
Sendmail 配置实例介绍如下:
sina.com 10.0.0.20 163.com 10.0.0.30
MX:dns.sina.com (hostname) MX:smtp.163.com(hostname)
邮件服务器A(MTA) 邮件服务器B(MTA)
DNS解析系统
邮件客户端A(MUA) 邮件客户端B(MUA)
目标:
1.两台邮件服务器分别属于sina.com和163.com;各集成smtp和pop3服务功能。
2.其中sina的邮件服务器被同时配置为DNS服务器集成DNS功能并能够解析两个域的所有主机。
3.最终两台服务器实现两个域的邮件转发,经过OUTLOOK测试成功
4.其他附加功能在后。
步骤:
1.配置DNS服务。基本配置:hostname=dns.sina.com;ipaddr=10.0.0.20
DNS服务相关文件为:
#/etc/named.conf中添加正向、反向解析区域:
zone "sina.com" IN {
type master;
file "sina.com.zone";
allow-update { none; };
};
zone "163.com" IN {
type master;
file "163.com.zone";
allow-update { none; };
};
zone "0.0.10.in-addr.arpa" IN {
type master;
file "sina.com.local";
allow-update { none; };
};
之后区域文件sina.com.zone、163.com.zone和163.com.local内容如下:
$TTL 86400
$ORIGIN sina.com.
@ 1D IN SOA dns.sina.com. root.sina.com. (
42 ; serial (d. adams)
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
1D IN NS dns.sina.com.
1D IN MX 5 dns.sina.com.
dns 1D IN A 10.0.0.20
smtp 1D IN CNAME dns
pop3 1D IN CNAME dns
$TTL 86400
$ORIGIN 163.com.
@ 1D IN SOA dns.sina.com. root.sina.com. (
42 ; serial (d. adams)
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
1D IN NS dns.sina.com.
1D IN MX 5 smtp.163.com.
smtp 1D IN A 10.0.0.30
pop3 1D IN CNAME smtp
$TTL 86400
@ IN SOA dns.sina.com. root.sina.com. (
1997022700 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum
IN NS dns.sina.com.
20 IN PTR smtp.sina.com.
20 IN PTR pop3.sina.com.
30 IN PTR smtp.163.com.
30 IN PTR pop3.163.com.
#service sendmail restart
解析测试。
