mail 配置

postfix(MTA smtp)+dovecot(pop3/imap)+squirrelmail(webmail)＋apache+php+bind

1.設置主機名
[root@www ~]# vim /etc/sysconfig/network
[root@www ~]# hostname mail.baidu.com
[root@www ~]# vim /etc/hosts
192.168.0.1 www.baidu.com www baidu.com

2.配置DNS
[root@www ~]# yum -y remove bind

[root@www ~]# yum -y install bind

[root@mail ~]# vim /etc/named.conf
listen-on port 53 { 127.0.0.1; any; };
allow-query { localhost; any; };

[root@mail ~]# vim /etc/named.rfc1912.zones
zone "baidu.com" IN {
type master;
file "baidu.com.zone";
allow-update { none; };
};
[root@mail ~]# named-checkconf /etc/named.conf
[root@mail ~]# cd /var/named/
[root@mail named]# cp named.localhost baidu.com.zone -a

[root@mail named]# vim baidu.com.zone

$TTL 1D
@ IN SOA dns1.baidu.com. root.baidu.com. (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
@ NS dns1.baidu.com.
dns1 A 192.168.0.1
www A 192.168.0.100

@ MX 5 mail.baidu.com.
mail A 192.168.0.1
pop A 192.168.0.1
imap A 192.168.0.1

[root@mail named]# named-checkzone baidu.com /var/named/baidu.com.zone
zone baidu.com/IN: loaded serial 0
OK
[root@mail named]# service named start
Starting named: [ OK ]
[root@mail named]# chkconfig named on

[root@mail named]# nslookup
> server
Default server: 192.168.0.17
Address: 192.168.0.17#53
> exit

[root@mail named]# vim /etc/resolv.conf
nameserver 192.168.0.1

[root@mail named]# nslookup
> server
Default server: 192.168.0.1
Address: 192.168.0.1#53
> set type=ns
> baidu.com
Server: 192.168.0.1
Address: 192.168.0.1#53

baidu.com nameserver = dns1.baidu.com.
> set type=mx
> baidu.com
Server: 192.168.0.1
Address: 192.168.0.1#53

baidu.com mail exchanger = 5 mail.baidu.com.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

3.配置postfix

[root@mail ~]# rpm -qa | grep postfix
postfix-2.6.6-2.el6.x86_64

75 myhostname = mail.baidu.com
83 mydomain = baidu.com
99 myorigin = $mydomain
116 inet_interfaces = all
119 inet_protocols = ipv4
164 mydestination = $myhostname, $mydomain, localhost
264 mynetworks = 192.168.0.0/24
419 home_mailbox = Maildir/

[root@mail ~]# service postfix restart
Shutting down postfix: [FAILED]
Starting postfix: [FAILED]

[root@mail ~]# postfix stop
postfix/postfix-script: stopping the Postfix mail system
[root@mail ~]# postfix start
postfix/postfix-script: starting the Postfix mail system
[root@mail ~]# netstat -tnlp |grep :25
tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN 8731/master

4.使用dovecot實現110/143收信
# yum -y install dovecot
[root@mail ~]# /etc/init.d/dovecot start
正在啓動 Dovecot Imap： [確定]
[root@mail ~]# chkconfig dovecot on
tcp 0 0 0.0.0.0:110 0.0.0.0:* LISTEN 8789/dovecot
tcp 0 0 0.0.0.0:143 0.0.0.0:* LISTEN 8789/dovecot
tcp 0 0 0.0.0.0:993 0.0.0.0:* LISTEN 8789/dovecot
tcp 0 0 0.0.0.0:995 0.0.0.0:* LISTEN 8789/dovecot
tcp 0 0 :::110 :::* LISTEN 8789/dovecot
tcp 0 0 :::143 :::* LISTEN 8789/dovecot
tcp 0 0 :::993 :::* LISTEN 8789/dovecot
tcp 0 0 :::995 :::* LISTEN 8789/dovecot
