RedHat 5.4下构建postfix全功能电子邮（六）
RedHat 5.4下构建postfix全功能电子邮（六）-postfix详细配置一、配置 Postfix
查看模块，#postconf -m |grep mysql 返回值有mysql，说明可以支持mysql 数据库的查询表
# cd
# postconf -m |grep mysql
mysql
1、修改配置文件
# vim /etc/postfix/main.cf
162-163行需要注释掉
162 #mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain,
163 # mail.$mydomain, www.$mydomain, ftp.$mydomain
652 virtual_mailbox_base = /mailbox
653 virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf
654 virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf
655 virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf
656 virtual_uid_maps = static:1000
657 virtual_gid_maps = static:1000
658 virtual_transport = virtual
# cd /usr/local/src/extman-1.1/docs/
# cp mysql_virtual_* /etc/postfix/
二、虚拟用户设置SMTP发信认证
2.1 软件安装
注意：确认系统中的rpm格式的mysql 软件被卸载
# cd /soft
# tar -jxvf courier-authlib-0.62.4.tar.bz2 -C /usr/local/src/
# cd /usr/local/src/courier-authlib-0.62.4/
# ./configure --prefix=/usr/local/courier-authlib --without-stdheaderdir --with-authmysql --with-redhat --with-mysql-libs=/usr/local/mysql/lib/mysql --with-mysql-includes=/usr/local/mysql/include/mysql
/*install-configure #生成默认配置文件authmysqlrc 和 authdaemonrc*/
# make && make install && make install-configure
2.2、 添加courier-authlib的库文件路径
# vim /etc/ld.so.conf.d/courier-authlib.conf
/usr/local/courier-authlib/lib/courier-authlib
# ldconfig -v |grep courier-authlib
/usr/local/courier-authlib/lib/courier-authlib:
2.3、 修改authdaemonrc主配置文件
# cd /usr/local/courier-authlib/etc/authlib
# cp authdaemonrc authdaemonrc.bak
# vim authdaemonrc
27 authmodulelist="authmysql"
34 authmodulelistorig="authmysql"
# chmod -R 755 /usr/local/courier-authlib/var/spool/authdaemon/
2.4、 修改authmysqlrc 文件
# cd /usr/local/courier-authlib/etc/authlib
# cp authmysqlrc authmysqlrc.bak
# vim authmysqlrc
26 MYSQL_SERVER localhost
27 MYSQL_USERNAME extmail
28 MYSQL_PASSWORD extmail
49 MYSQL_SOCKET /tmp/mysql.sock
56 MYSQL_PORT 3306
68 MYSQL_DATABASE extmail
83 MYSQL_USER_TABLE mailbox
92 MYSQL_CRYPT_PWFIELD password
113 MYSQL_UID_FIELD uidnumber
119 MYSQL_GID_FIELD gidnumber
128 MYSQL_LOGIN_FIELD username
133 MYSQL_HOME_FIELD concat('/mailbox/',homedir)
139 MYSQL_NAME_FIELD name
150 MYSQL_MAILDIR_FIELD concat('/mailbox/',maildir
2.5、 复制courier-authlib脚本，并启动courier-authlib服务。
# cd /usr/local/src/courier-authlib-0.62.4/
# cp courier-authlib.sysvinit /etc/init.d/courier-authlib
# cd
# chmod 755 /etc/init.d/courier-authlib
# chkconfig --add courier-authlib
# chkconfig --level 2345 courier-authlib on
# chkconfig --list courier-authlib
courier-authlib 0:off1:off2:on 3:on 4:on 5:on 6:off
# service courier-authlib start
Starting Courier authentication services: authdaemond
# ps -aux |grep courier-authlib
三、修改Cyrus sasl 设置
3.1、添加如下文件
# vim /usr/lib/sasl2/smtpd.conf
pwcheck_method: authdaemond
mech_list:PLAIN LOGIN
authdaemond_path:/usr/local/courier-authlib/var/spool/authdaemon/socke
四、修改Dovecot配置
4.1、修改Dovecot
# vim /etc/dovecot.conf
208 mail_location = maildir:/mailbox/%d/%n/Maildir
790 auth default {
795 mechanisms = plain
828 # passdb pam {
857 # }
899 passdb sql {
901 args = /etc/dovecot-mysql.conf
902 }
962 userdb sql {
964 args = /etc/dovecot-mysql.conf
965 }
4.2、打开一行，postfix的配置文件也要该（可能已经改过）
# vim /etc/postfix/main.cf
415 home_mailbox = Maildir/
10.2 建立数据查询配置文件，手动产生/etc/dovecot-mysql.conf文件：
# vim /etc/dovecot-mysql.conf
1 ver = mysql
2 connect = host=localhost dbname=extmail user=extmail password=extmail
3 default_pass_scheme = CRYPT
4 password_query = SELECT username AS user,password AS password FROM m ailbox WHERE username = ‘%u’
5 user_query = SELECT maildir, uidnumber AS uid, gidnumber AS gid FRO M mailbox WHERE username = ‘%u’
五、建立虚拟用户
5.1、建立邮箱目录并调整权限
# mkdir -p /mailbox/extmail.org/postmaster/Maildir
# cd /mailbox/extmail.org/postmaster/Maildir/
# chown -R postfix:postfix /mailbox/
5.2、启动服务
# dovecot
Fatal: Dovecot is already running with PID 29275 (read from /usr/local/var/run/dovecot/master.pid)
# /usr/local/sbin/dovecot -c /etc/dovecot.conf
Fatal: Dovecot is already running with PID 29275 (read from /usr/local/var/run/dovecot/master.pid)
5.3、虚拟用户测试
确认authlib服务
# /usr/local/courier-authlib/sbin/authtest -s login postmaster@extmail.org extmail
Authentication succeeded.
Authenticated: postmaster@extmail.org (uid 1000, gid 1000)
Home Directory: /mailbox/extmail.org/postmaster
Maildir: /mailbox/extmail.org/postmaster/Maildir/
Quota: (none)
Encrypted Password: $1$phz1mRrj$3ok6BjeaoJYWDBsEPZb5C0
Cleartext Password: extmail
Options: (none)
