postfix之dovecot

dovecot-1.0.rc14安装

注：我的系统是RHEL4
一、RPM格式
1。安装RPM包；
2。编辑/etc/dovecot.conf
其中，修改
protocols = imap pop3
passdb passwd {
}
passdb shadow {
  }
3。启动
#service dovecot start

二、tar.gz包的安装
1。下载地址：(目前最新版本)
http://www.dovecot.org/releases/dovecot-1.0.rc14.tar.gz

2。安装：
#tar zxvf dovecot-1.0.rc14.tar.tar
#cd dovecot-1.0.rc14
#./configure --prefix=/usr/local/dovecot --sysconfdir=/usr/local/etc --with-mysql --without-ssl --disable-ipv6
#make
#make install
# cp /usr/local/etc/dovecot-example.conf /usr/local/etc/dovecot.conf

3。建立启动进程所依赖的用户
# useradd -s /bin/false -d /dev/null dovecot

4。修改配置文件
编辑/usr/local/etc/dovecot.conf
其中，修改
protocols = imap pop3
ssl_disable = yes
passdb passwd {
}
passdb shadow {
  }
5。启动
#/usr/local/dovecot/sbin/dovecot

6。可以把启动命令写进/etc/rc.d/rc.local文件，以使得系统启动时能自动启动服务。
#echo "/usr/local/dovecot/sbin/dovecot" >> /etc/rc.d/rc.local

7。验正
