Mail system server Setup record (iv) (POSTFIX+CYRUS-SASL+COURIER-AUTHLIB+DOVECOT+EXTMAIL+MYSQL)

8. Install Apache Http Server:

[email protected] ~]# Yum install httpd

9. Download Extmail and Extman and initialize the Extmail database using the MySQL script provided by Extman

Visit the Extmail official website (http://www.extmail.org/) to download the Extmail and Extman package, unzip:

[Email protected] ~]# tar-xf extmail-1.2.tar.gz[[email protected] ~]# tar-xf extman-1.1.tar.gz

Create a new/var/www/extsuite directory and move the extracted extmail and Extman directories to this directory:

[Email protected] ~]# Mkdir-pv/var/www/extsuite[[email protected] ~]# mv Extmail-1.2/var/www/extsuite/extmail[[email Protected] ~]# MV Extman-1.1/var/www/extsuite/extman

Entering the/var/www/extsuite/extman/docs directory, you can find 2 files named SQL-terminated:

[[email protected] ~]# cd/var/www/extsuite/extman/docs/[[email protected] docs]# ls *.sqlextmail.sql init.sql

Two are MySQL scripts, Extmail.sql used to build Extmail database and related table structure; Init.sql is used to insert some initialization data and run as root using the MySQL command:

[Email protected] ~]# mysql-uroot <extmail.sql[[email protected] ~]# mysql-uroot <init.sql

At this point MySQL has established the Extmail database, and the virtual user, virtual domain-related table structure has been established.

Note: If MySQL is a version above 5.1, then the above script may run with errors and need to modify "Type=myisam" in the script to "Engine=innodb".

10. Configuring the Cyrus-authlib AUTHMYSQLRC file

In this case, MySQL has generated the Extmail database, and established a Extmail user to access the Extmail database, so you can configure the cyrus-authlib MySQL configuration file/ETC/AUTHMYSQLRC:

[[email protected] ~]# vi /etc/authmysqlrcmysql_server             localhost     #mysql服务器所在地址MYSQL_USERNAME            extmail     #访问mysql的用户名MYSQL_PASSWORD           extmai     #访问mysql的用户口令MYSQL_ socket    /var/lib/mysql/mysql.sock     #mysql套接字文件所在地址MYSQL_PORT                3306    # MySQL Service listener Port mysql_opt                0     #可选项MYSQL_DATABASE           extmail      #库名, the script provided by Extman is based on the Extmail library mysql_user_table         mailbox     #要访问的虚拟用户信息所在的表名MYSQL_CRYPT_PWFIELD      password      #验证虚拟用户所用到的口令, use the password field of the mailbox table in the Extmail library to represent mysql_uid_field          2525     #启动mysql服务的系统用户的UID because the postfix user calls Postfix and Courier-authlib, So it should be the Postfix user's uidmysql_gid_field         2525      #启动mysql服务的系统用户的GIDMYSQL_LOGIN_FIELD        username      #虚拟用户名, use the username field of the mailbox table in the Extmail library to represent mysql_home_field         Concat ('/mailbox/', homedir)      #虚拟用户家目录的地址, specific user's home directory address using/mailbox/+ Homedir field values stored in the mailbox table of the Extmail library are stitched together into mysql_name_field        name      #虚拟用户姓名MYSQL_MAILDIR_FIELD      concat ('/mailbox/', MAILDIR)       #虚拟用户存放邮件的地址, the specific user's home directory address using/mailbox/+ stored in extMail Library mailbox table Maildir field values are stitched together 

11. Configure Postfix to support virtual users

To edit the postfix configuration file/etc/postfix/main.cf, add the following configuration parameters:

#virtualvirtual_mailbox_base =/mailbox #配置虚拟用户邮箱所在基本目录virtual_mailbox_maps = Mysql:/etc/postfix/mysql_virtual_ MAILBOX_MAPS.CF #配置虚拟用户邮箱地址virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf # Configure the virtual domain virtual_alias_domains =virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf #配置虚拟用户别名virtual_ Uid_maps = static:2525 #访问所有虚拟邮件用户时, need to use the operating system user for proxy access, the agent access system user Uidvirtual_gid_maps = static:2525 #访问所有虚拟邮件用户时, need to use the operation system User for proxy access, System user Gidvirtual_transport = Virtual #支持虚拟用户所使用的postfix驱动为virtual

Note: If you enable quota control for a virtual user's mailbox, you can add the following configuration parameters:

Message_size_limit = 14336000 #单条邮件大小的最大值, in bytes Virtual_mailbox_limit = 52428800 #单用户邮箱容量的最大值, in bytes

In the above configuration, the Virtual_mailbox_maps,virtual_mailbox_domains,virtual_alias_maps parameter value format is MySQL: Config file address, Indicates that postfix will look for table records in MySQL to get the corresponding parameter values, and the Postfix lookup table type is mysql-enabled:

[Email protected] ~]# Postconf-m | grep mysqlmysql

The corresponding virtual user mailbox address, virtual domain, virtual user alias configuration file, Extman has been provided, location under/var/www/extsuite/extman/docs/, copy it to the/etc/postfix/directory:

[Email protected] ~]# cd/var/www/extsuite/extman/docs/[[email protected] docs]# ls-l mysql_virtual_*-rw-r--r--. 1 postfix postfix 166 DEC 2005 Mysql_virtual_alias_maps.cf-rw-r--r--. 1 postfix postfix 168 mysql_virtual_domains_maps.cf-rw-r--r--. 1 postfix postfix 2005 Mysql_virtual_limit_maps.cf-rw-r--r--. 1 postfix postfix 172 Dec 2005 Mysql_virtual_mailbox_maps.cf-rw-r--r--. 1 postfix postfix 173 Mar 7 Mysql_virtual_sender_maps.cf[[email protected] docs] #cp mysql_virtual_*/etc/postfix/

12. Modify the CYRUS-SASL configuration file for smtpd/usr/lib64/sasl2/smtpd.conf, which is taken over by the Authdaemond process (provided by the Courier-authlib service):

[Email protected] ~]# Vi/usr/lib64/sasl2/smtpd.confpwcheck_method:authdaemondmech_list:plain Loginauthdaemond_ Path:/var/spool/authdaemon/socket #authdaemond使用套接字通信的套接字文件所在路径

The next article will cover configuration Dovecot to support access to MySQL to complete the collection certification work, as well as the deployment of Extmail and the hypervisor Extman
