wget http://surfnet.dl.sourceforge.net/sourceforge/courier/courier-imap-4.1.1.tar.bz2

tar jvxf courier-imap-4.1.1.tar.bz2

./configure --prefix=/usr/local/courier-imap --with-redhat --enable-unicode --disable-root-check \
--with-trashquota --without-ipv6 CPPFLAGS='-I/usr/local/courier-authlib/include' \
COURIERAUTHCONFIG='/usr/local/courier-authlib/bin/courierauthconfig' \
CPPFLAGS='-I/usr/local/courier-authlib/include'

#如果编译courier-authlib没有安装在默认路径，必须指定这个，如果之前编译courier-authlib加了--without- stdheaderdir，就不需要指定了

make

make install

cp /usr/local/courier-imap/etc/imapd.dist /usr/local/courier-imap/etc/imapd
cp /usr/local/courier-imap/etc/imapd-ssl.dist /usr/local/courier-imap/etc/imapd-ssl
cp /usr/local/courier-imap/etc/pop3d.dist /usr/local/courier-imap/etc/pop3d
cp /usr/local/courier-imap/etc/pop3d-ssl.dist /usr/local/courier-imap/etc/pop3d-ssl

 配置Courier-IMAP，为用户提供pop3服务：
vi /usr/local/courier-imap/etc/pop3d
POP3DSTART=yes
 注：如果你想为用户提供IMAP服务，可以在"/usr/local/courier-imap/etc/imapd"文件中设置"IMAPDSTART=yes"。

 设置Courier-IMAP开机自动运行：
cp courier-imap.sysvinit /etc/rc.d/init.d/imapd
chmod 755 /etc/rc.d/init.d/imapd
chkconfig --add imapd

测试POP3：
