RPM-IVH epel-release-latest-7.noarch.rpm

Third, installation Postfix

1, uninstall the system comes with Postfix, delete postfix user, reassign uid, GID create new user Postfix,postdrop

Yum Remove postfix-y

Userdel postfix

Groupdel Postdrop

Groupadd-g 2525 Postfix

2. Change the Extmail configuration file

Cd/var/www/extsuite/extmail

CP Webmail.cf.default WEBMAIL.CF

Vim WEBMAIL.CF

Sys_sess_dir =/tmp/extmail

Sys_upload_tmpdir =/tmp/extmail/upload

Sys_user_lang = ZH_CN

Sys_min_pass_len = 8

Sys_maildir_base =/var/mailbox

Sys_mysql_user = Extmail

Sys_mysql_pass = Extmail

Sys_mysql_socket =/var/lib/mysql/mysql.sock

sys_mysql_table = Mailbox

Sys_mysql_attr_username = USERNAME

Sys_mysql_attr_domain = DOMAIN

SYS_MYSQL_ATTR_PASSWD = password

Sys_authlib_socket =/usr/local/courier-authlib/var/spool/authdaemon/socket

3. Set up temporary files directory and Session Directory

Mkdir-p/tmp/extmail/upload

Chown-r postfix.postfix/tmp/extmail/

Vii. installation of Extman

Tar XF extman-1.1.tar.gz-c/var/www/extsuite/

cd/var/www/extsuite/

MV Extman-1.1/extman

2. Change the Extman configuration file

CD extman/

CP Webman.cf.default WEBMAN.CF

3. Change the CGI directory belongs to the main genus Group

Chown-r postfix.postfix/var/www/extsuite/extman/cgi/

Chown-r postfix.postfix/var/www/extsuite/extmail/cgi/

4. Import the database

Vim Docs/extmail.sql

:% s/type/engine/g

Vim/etc/my.cnf

# Recommended in standard MySQL setup

#sql_mode =no_engine_substitution,strict_trans_tables//Take this line and restart MySQL, it is important to note that after the database import is successful, this is not to be removed from the comment, Otherwise, MySQL will not start up.

Mysql-uroot < Docs/extmail.sql

Mysql-uroot < Docs/init.sql

5. Create database user Extmail and grant permissions

GRANT all on extmail.* to [email protected] '% ' identified by ' extmail ';

FLUSH privileges;

6. Copy the configuration file mentioned in four-4

cd/var/www/extsuite/extman/docs/

CP mysql_virtual_*/etc/postfix/

Mkdir/tmp/extman

Chown-r postfix.postfix/tmp/extman/

7, start Postfix, Dovecot, SASLAUTHD

Service Postfix Restart

Open the 465 (SMTPS) port, you need to do the following

Modify the/etc/postfix/master.cf file

Under SMTP inet n-n--smtpd line, add the following line:

Smtps inet n-n--Smtpd-o Smtpd_tls_wrappermode=yes
