Linux服务器中邮件服务器dovecot怎么用

[root@localhost ~]# rpm -qa | grep dovecot

[root@localhost ~]# yum install -y dovecot

Installed:

  dovecot.i686 1:2.0.9-22.el6

[root@localhost ~]# 

[root@localhost ~]# gedit /etc/dovecot/dovecot.conf

protocols = imap pop3 lmtp    //这行默认被注释了，必须去掉注释。这里表示启用了imap pop3 lmtp协议

listen=*     //监听所有的ipv4接口

login_trusted_networks = 192.168.0.0/24     //允许登录的网段

[root@localhost pub]# gedit /etc/dovecot/conf.d/10-mail.conf

# mbox是内部邮箱，属于dovecot持有。而通常IMAP协议支持多种邮箱，因此其他邮箱的内容就存储在/var/mail/%u

mail_location = mbox:~/mail:INBOX=/var/mail/%u

[root@localhost ~]# su david      //切换到david

[david@localhost root]$ cd /home/david/    //跳转到家目录

[david@localhost ~]$ mkdir -p mail/.imap/INBOX     //创建邮件目录

[root@localhost ~]# gedit /etc/sysconfig/iptables
