3）编辑dovecot通过mysql认证的文件
[root@node1 conf.d]# vi /etc/dovecot-mysql.conf
driver = mysql
connect = host=localhost dbname=extmail user=extmail password=extmail
default_pass_scheme = CRYPT
password_query = SELECT username AS user,password AS password FROM mailbox WHERE username = '%u'
user_query = SELECT maildir, uidnumber AS uid, gidnumber AS gid FROM mailbox WHERE username = '%u'
——安装courier-authlib
1）下载安装courier-authlib
[root@node1 soft]# wget http:
//jaist.dl.sourceforge.net/project/courier/authlib/0.66.1/courier-authlib-0.66.1.tar.bz2
[root@node1 soft]# tar fvx courier-authlib-0.66.1.tar.bz2
[root@node1 soft]# cd courier-authlib-0.66.1
[root@node1 courier-authlib-0.66.1]# ./configure \
--prefix=/usr/local/courier-authlib \
--sysconfdir=/etc \
--without-authpam \
--without-authshadow \
--without-authvchkpw \
--without-authpgsql \
--with-authmysql \
--with-mysql-libs=/usr/lib64/mysql \
--with-mysql-includes=/usr/include/mysql \
--with-RedHat \
--with-authmysqlrc=/etc/authmysqlrc \
--with-authdaemonrc=/etc/authdaemonrc \
--with-mailuser=postfix
[root@node1 courier-authlib-0.66.1]# make && make install
2）配置courier-authlib
[root@node1 courier-authlib-0.66.1]# chmod 755 /usr/local/courier-authlib/var/spool/authdaemon
[root@node1 courier-authlib-0.66.1]# cp /etc/authdaemonrc.dist /etc/authdaemonrc
[root@node1 courier-authlib-0.66.1]# cp /etc/authmysqlrc.dist /etc/authmysqlrc
[root@node1 courier-authlib-0.66.1]# vi /etc/authdaemonrc
authmodulelist="authmysql"
authmodulelistorig="authmysql"
[root@node1 courier-authlib-0.66.1]# vi /etc/authmysqlrc
MYSQL_SERVER localhost
MYSQL_USERNAME extmail
MYSQL_PASSWORD extmail
MYSQL_SOCKET /var/lib/mysql/mysql.sock
MYSQL_PORT 3306
MYSQL_DATABASE extmail
MYSQL_USER_TABLE mailbox
MYSQL_CRYPT_PWFIELD password
DEFAULT_DOMAIN test.com
MYSQL_UID_FIELD '2525'
MYSQL_GID_FIELD '2525'
MYSQL_LOGIN_FIELD username
MYSQL_HOME_FIELD concat('/var/mailbox/',homedir)
MYSQL_NAME_FIELD name
MYSQL_MAILDIR_FIELD concat('/var/mailbox/',maildir)
3）设置courier-authlib开机启动
[root@node1 courier-authlib-0.66.1]# cp courier-authlib.sysvinit /etc/init.d/courier-authlib
[root@node1 courier-authlib-0.66.1]# chmod +x /etc/init.d/courier-authlib
[root@node1 courier-authlib-0.66.1]# chkconfig --add courier-authlib
[root@node1 courier-authlib-0.66.1]# chkconfig courier-authlib on
[root@node1 courier-authlib-0.66.1]# echo "/usr/local/courier-authlib/lib/courier-authlib" >> /etc/ld.so.conf.d/courier-authlib.conf
[root@node1 courier-authlib-0.66.1]# ldconfig
[root@node1 courier-authlib-0.66.1]# service courier-authlib start
Starting Courier authentication services: authdaemond
4）设置smtpd认证
[root@node1 courier-authlib-0.66.1]# vi /usr/lib64/sasl2/smtpd.conf
pwcheck_method: authdaemond
log_level: 3
mech_list: PLAIN LOGIN
authdaemond_path:/usr/local/courier-authlib/var/spool/authdaemon/socket
5）配置postfix支持SMTP
1234567 [root@node1 dovecot]# vi /etc/postfix/main.cf
smtpd_sasl_auth_enable = yes
smtpd_sasl_local_domain = ''
smtpd_recipient_restrictions = permit_mynetworks,permit_sasl_authenticated,reject_unauth_destination
broken_sasl_auth_clients=yes
smtpd_client_restrictions = permit_sasl_authenticated
smtpd_sasl_security_options = noanonymous
