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
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
(1)验正POP3
#telnet localhost 110
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
+OK Dovecot ready.
(2)验正imap
#telnet localhost 143
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
* OK Dovecot ready.
