本系统采用目前企业比较普遍的postfix＋extmail系统，其中管理采用extman系统，使用环境为apache+mysql,邮件系统认证使用mysql方式，POP3支持用courier软件。全套系统用的开源环境，测试收发邮件及客户端pop3均正常，认证密码采用md5crypt加密。

加入：
user = extmail
password = extmail
#hosts = localhost
hosts = 219.224.99.244

加入：
user = extmail
password = extmail
#hosts = localhost
hosts = 219.224.99.244
dbname = extmail
table = mailbox
select_field = quota
where_field = username
additional_conditions = AND active = ‘1‘
3.2配置smtp
#vi /etc/default/saslauthd
将start=no改成yes
#vi /etc/postfix/sasl/smtpd.conf
加入：
pwcheck_method: authdaemond
log_level: 7
mech_list: plain login
authdaemond_path:/var/run/courier/authdaemon/socket
加入：
auth required pam_mysql.so user=extmail passwd=extmail host=202.205.109.7 db=extmail table=mailbox usercolumn=username passwdcolumn=password crypt=1
account sufficient pam_mysql.so user=extmail passwd=extmail host=202.205.109.7 db=extmail table=mailbox usercolumn=username passwdcolumn=password crypt=1
3.3配置pop3
修改下面一些地方：
POP3AUTH="" 改为POP3AUTH=" CRAM-MD5"
#mv /etc/courier/authdaemonrc /etc/courier/authdaemonrc.bak
#vi /etc/courier/authdaemonrc
加入：
authmodulelist="authmysql"
authmodulelistorig="authmysql"
version="authdaemond.mysql"
daemons=5
subsystem=mail
DEBUG_LOGIN=2
DEFAULTOPTIONS=""
authdaemonvar=/var/run/courier/authdaemon
#vi /etc/courier/authmodulelist
修改认证模式为authmysql
# mv /etc/courier/authmysqlrc /etc/courier/authmysqlrc.bak
#vi /etc/courier/authmysqlrc
加入：
MYSQL_SERVER 219.224.99.244
MYSQL_PORT 3306
MYSQL_USERNAME extmail
MYSQL_PASSWORD extmail
MYSQL_SOCKET /var/run/mysqld/mysqld.sock
MYSQL_DATABASE extmail
MYSQL_USER_TABLE mailbox
MYSQL_CRYPT_PWFIELD password
MYSQL_UID_FIELD uidnumber
MYSQL_GID_FIELD gidnumber
MYSQL_LOGIN_FIELD username
MYSQL_HOME_FIELD homedir
MYSQL_NAME_FIELD name
MYSQL_MAILDIR_FIELD maildir
MYSQL_QUOTA_FIELD quota
MYSQL_SELECT_CLAUSE SELECT username,password,"",uidnumber,gidnumber,
CONCAT(‘/home/domains/‘,homedir),
CONCAT(‘/home/domains/‘,maildir),
quota,
name
FROM mailbox
WHERE username = ‘$(local_part)@$(domain)‘
3.4 配置webmail 3.4.1 配置apache2
#vi /etc/apache2/sites-enabled/vip.eol.cn
<VirtualHost *>
ServerName mail.vip.eol.cn
DocumentRoot /var/www/extsuite/extmail/html
ScriptAlias /extmail/cgi /var/www/extsuite/extmail/cgi
Alias /extmail /var/www/extsuite/extmail/html
ScriptAlias /extman/cgi /var/www/extsuite/extman/cgi
Alias /extman /var/www/extsuite/extman/html
SuexecUserGroup postfix postfix
<Directory /var/www/extsuite>
Options Indexes FollowSymLinks
AllowOverride None
Allow from all
</Directory>
</VirtualHost>
注意：suexec模块安装的时候，debian默认用户为www-data,目录为/var/www目录，手工编译安装可以自己指定参数
# ln -s /etc/apache2/mods-available/suexec.load /etc/apache2/mods-enabled/
34.2 配置extmail/extman
导入数据库：
#cd /opt/distfiles/
#tar zxvf extman-1[1][1].0.1.tar.gz
#cd extman-1.0.1/docs/
#mysql -uroot < extmail.sql
#mysql -uroot < init.sql
说明：
此时已经创建了extmail数据库，并授权了extmail/extmail和webman/webman帐户，默认extman管理账号为root@extmail.org/extmail*123*
# chown -R postfix.postfix /var/www/extsuite/extmail/cgi/
# chown -R postfix.postfix /var/www/extsuite/extman/cgi/
#mkdir /var/www/ extsuite
#mv /opt/distfiles/extmail /var/www/extsuite
#mv /opt/distfiles/extman /var/www/extsuite
配置extmail
#cd /var/www/extsuite/extmail
#cp webmail.cf.default webmail.cf
#vi webmail.cf
修改其中的数据库配置和smtp服务器配置以及默认语言配置：
SYS_USER_LANG = zh_CN
SYS_CRYPT_TYPE = md5crypt
SYS_MYSQL_USER = extmail
SYS_MYSQL_PASS = extmail
SYS_MYSQL_DB = extmail
SYS_MYSQL_HOST = 219.224.99.244
SYS_MYSQL_SOCKET = /var/run/mysqld/mysqld.sock
#mkdir /home/domains
# chown -R postfix.postfix /home/domains/
配置extman
#cd /var/www/extsuite/extman
#cp webman.cf.default webman.cf
SYS_LANG = zh_CN
SYS_MYSQL_USER = webman
SYS_MYSQL_PASS = webman
SYS_MYSQL_DB = extmail
SYS_MYSQL_HOST = localhost
SYS_MYSQL_SOCKET = /var/run/mysqld/mysqld.sock
图形日志：
注意：
debian的邮件日志为/var/log/mail.log，而mailgraph-init脚本定义的日志为mailog，需要手工修改，或者链接一个文件，建议修改脚本中的配置为MAIL_LOG=/var/log/mail.log
#cp Cr /var/www/extsuite/extman/addon/mailgraph_ext /usr/local/
# /usr/local/mailgraph_ext/mailgraph-init start
#/var/www/extsuite/extman/daemon/cmdserver --daemon
