中小规模POSTFIX邮件系统

1．安装webmin
下载webmin-1.070.tar.gz
#tar zxvf webmin-1.070.tar.gz
#cd webmin-1.070
#./setup.sh
安装后可以对mysql数据库进行管理，比如添加用户，向表里添加数据。

2．1、安装mysql数据库
本系统使用的是FreeBSD 4.7下ports安装的mysql数据库
（当时使用原码安装时在安装postfix时出错，所以使用ports安装就解决了该问题）。

#cd /usr/ports/databases/mysql323-server/
#make install
#cd work/mysql-3.23.52/
#scripts/mysql_install_db
#cp support-files/my-medium.cnf /etc/my.cnf
#echo “/usr/local/bin/safe_mysqld --user=mysql &” >> /etc/rc.local
#/usr/local/bin/safe_mysqld --user=mysql & 启动mysql服务

2．2、设置数据库

2.2.1、添加mysql用户：

1、使用webmin－>mysql数据库服务器－>用户权限，添加用户postfix，
密码postfix，主机localhost，并设置拥有相应的权限。

2、使用SQL语句添加用户：
#cd /usr/local/bin
#./mysql –D mysql –p
Password:
mysql>INSERT INTO user (host,user,password)
->VALUES (‘localhost’,‘postfix’,’’);
Query OK. I row affected (0.00 sec)
mysql>UPDATA user SET password=password(‘postfix’)
->WHERE user=’postfix’;
Rows matched: 1 Changed: 1 Warnings: 0
mysql>FLUSH PRIVILEGES;
Query OK. 0 rows affected (0.01 sec)
mysql>GRANT select,insert,update on mail.* TO postfix
Query OK. 0 rows affected (0.01 sec)
mysql>exit

2.2.2、向数据库中添加表

#cd /usr/local/bin/
#ee postfix.sql

CREATE DATABASE;
GRANT ALL ON mail.* mail@localhost IDENTIFIED BY “postfix”;
FLUSH PRIVILEGES;
use mail;
CREATE TABLE forward (
username varchar(255) NOT NULL default ‘’, //本机地址
forward_addr varchar(255) default NULL, //转发地址
PRIMARY KEY (username)
) TYPE=MyISAM;
CREATE TABLE transport (
domain varchar(255) NOT NULL default ‘’, //邮件域
transport varchar(icon_cool.gif default NULL, //处理方式
PRIMARY KEY (domain)
) TYPE=MyISAM;
CREATE TABLE users (
username varchar(128) NOT NULL default ‘’, //用户名
domain varchar(128) NOT NULL default ‘’, //邮件域
address varchar(128) NOT NULL default ‘’, //邮件地址
password varchar(128) NOT NULL default ‘’, //用户密码（明文）
uid int(6) NOT NULL default ‘1024’, //uid
gid int(6) NOT NULL default ‘1024’， //gid
home varchar(255) NOT NULL default ‘/’, //home目录
maildir varchar(255) NOT NULL default ‘’, //maildir目录
quota varchar(255) NOT NULL default ‘’, //邮箱容量
mailok tinyint(3) NOT NULL default ‘1’,
bool1 tinyint(3) NOT NULL default ‘1’,
bool2 tinyint(3) NOT NULL default ‘1’,
PRIMARY KEY (address),
UNIQUE KEY address (address),
KEY address_2 (address)
) TYPE=MyISAM;

输入完毕后保存退出。
#./mysql –u postfix –p < postfix.sql
#password：postfix

2.2.3、向表中添加数据

#/usr/local/bin
#./mysql –u postfix –p
password:******
mysql>use mail
mysql>INSERT INTO transport (domain,transport)
->VALUES (’localhost.com’,’virtual:’);
mysql>INSERT INTO users (username,domain,address,password,uid,gid,
home,maildir,quota,mailok,bool1,bool2)
->VALUES (‘test’,’localhost.com’,’test.localhost.com’,
’test’,’1024’,’1024’,’/’,
’/var/postfix_mail/test/Maildir/’,’5000000’,’1’,’1’,’1’);
mysql>exit

3．安装CYRUS-SASL

#tar –zxvf cyrus-sasl-1.5.27
#cd cyrus-sasl-1.5.27
#./configure --with-pwcheck=/var/pwcheck --enable-login
--enable-plain
#make
#make install

#echo /usr/local/lib/ >> /etc/ld.so.conf
#echo /usr/local/lib/mysql/ >> /etc/ld.so.conf
#ldconfig

#cp /usr/local/include/* /usr/include
#cp /usr/local/lib/lib*.* /usr/lib

#ln –s /usr/local/lib/sasl /usr/lib/sasl
#ln –s /usr/local/include/mysql /usr/include/mysql
#ln –s /usr/local/lib/mysql /usr/lib/mysql

在/usr/local/lib/sasl下建立文件smtpd.conf,添加一下内容：
pwcheck_method:mysql
mysql_user:postfix
mysql_passwd:postfix
mysql_host:localhost
mysql_database:mail
mysql_table:users
mysql_uidcol:address
mysql_pwdcol:password

4.安装和设置postfix

4．1、安装postfix

4.4.1、编译/etc/rc.conf,设置sendmail_enable=”NO”

#mv /usr/bin/newaliases /usr/bin/newaliases.OFF
#mv /usr/bin/mailq /usr/bin/mailq.OFF
#mv /usr/sbin/sendmail /usr/sbin/sendmail.OFF
#pw groupadd postfix –g 1024
#pw groupadd postdrop –g 1025
#pw useradd postfix –u 1024 –g postfix
#echo ‘postfix:root’ >> /etc/aliases

4.4.2、安装postfix和相应的quota补丁

#tar zxvf postfix-1.1.11.tar.gz
#patch < postfix-1.1.11_quota_maildirsize.patch
#make –f Makefile.init makefiles ‘CCARGS=-DUSE_SASL_AUTH 
–DHAS_MYSQL –I/usr/include/mysql’ ‘AUXLIBS=-L/usr/lib/mysql 
–lmysqlclient –lasal –lz –lm’
#make
#make install 按照默认路径一路回车就可以安装成功postfix，如果出错，
在提示“tempdir”时输入：/tmp，这样一般就可以通过。

4．2、设置postfix

postfix默认安装到/etc/postfix目录下，设置文件也在这
#cd /etc/postfix

4.2.1、编译主配置文件main.cf

#ee main.cf 添加如下内容

#Base configure
myhostname = mail.localhost.com //本机的机器名
mydomain = local.com //域名
mynetworks = 127.0.0.0/8 192.168.0.0/16 //允许不经smtp认证能发信的ip段
home_mailbox = Maildir/ //使用的邮箱格式为Maildir/
smtpd_banner = Welcome to localhost.com mail system! //smtp的欢迎信息

#Mysql configure
transport_maps = mysql:/etc/postfix/transport.cf 
//指定那些域的邮件可以被postfix收下来
virtual_mailbox_base =/ //指定用户邮箱所在的根目录
virtual_uid_maps = mysql:/etc/postfix/ids.cf //指定postfix帐号的ID
virtual_gid_maps = mysql:/etc/postfix/gds.cf //指定postfix组的ID
virtual_mailbox_maps = mysql:/etc/postfix/users.cf //指定用户邮箱的目录
virtual_maps = mysql:/etc/postfix/forward.cf //指定自动转发邮件的设置
#Quota configure
message_size_limit = 5000000 //单个邮件大小的限制
virtual_mailbox_limit = 5000000 //默认的邮箱大小
virtual_mailbox_limit_maps = mysql:/etc/postfix/quota.cf 
//每个用户的邮箱大小
virtual_mailbox_limit_override = yes //是否允许覆盖默认的邮箱大小

#smtp configure
smtpd_sasl_auth_enable = yes
smtpd_sasl_local_domain = $myhostname
smtpd_recipient_restrictions = permit_mynetworks 
permit_sasl_authenticated permit_auth_destination reject
smtpd_sasl_security_options = noanonymous
smtpd_client_restrictions = permit_sasl_authenticated

inet_interfaces = all //监听所有端口
inet_interfaces = 192.168.80.21 //是外面的用户也可以发送邮件

4.2.2、查看master.cf文件必须包含下面一行

virtual unix - n n - - virtual

4.2.3、编译transport.cf

#touch transport.cf
#ee transport.cf 添加如下内容
user = postfix
password = postfix
dbname = mail
table = transport
select_field = transport
where_field = domain
hosts = localhost

4.2.4、编译ids.cf

#touch ids.cf
#ee ids.cf
user = postfix
password = postfix
dbname = mail
table = users
select_field = uid
where_field = address
hosts = localhost
4.2.5、编译gds.cf

#touch gds.cf
#ee gds.cf
user = postfix
password = postfix
dbname = mail
table = users
select_field = gid
where_field = address
hosts = localhost

4.2.6、编译forward.cf

#touch forward.cf
#ee forward.cf
user = postfix
password = postfix
dbname = mail
table = forward
select_field = forward_addr
where_field = username
hosts = localhost

4.2.7、编译users.cf

#touch users.cf
#ee users.cf
user = postfix
password = postfix
dbname = mail
table = users
select_field = maildir
where_field = address
hosts = localhost

4.2.8、编译quota.cf

#touch quota.cf
#ee quota.cf
user = postfix
password = postfix
dbname = mail
table = users
select_field = quota
where_field = address
hosts = localhost

4.3、启动postfix

#/usr/sbin/postfix start
postfix/postfix-script: starting the Postfix mail system

#echo “/usr/sbin/postfix start” >> /etc/rc.local

#telnet localhost 25
Connected to localhost.localhost.com.
Escape character is ‘^]’.
220 Welcome to localhost mail system!

4.4、测试postfix

4.4.1、建立mail邮件存放目录
#cd /var
#mkdir postfix_mail
#chown –R postfix:postfix /var/postfix_mail

4.4.2、使用客户端发邮件
此时可以使用客户端的foxmail或者outlook向用户test.localhost.com发送邮件，
然后到/var/postfix/test/Maildir/下查看邮件，如果能收到说明SMTP已经工作正常了，
如果有问题仔细检查自己的每个步骤。

5．安装设置courier-imap

5.1、安装courier-imap

#cd /usr/ports/mail/courier-imap
#make
#cd work/courier-imap-1.5.3
#./configure –with-db=db –without-socks –disable-root-check
#make
#make install
#/usr/lib/courier-imap/libexec/authlib/authdaemon start
#echo “/usr/lib/courier-imap/libexec/authlib/authdaemon start” >> /etc/rc.local

5.2、添加用户

#cd /usr/local/bin
#./mysql –D mysql –p
password:*******
mysql>INSERT INTO user (host,user,password)
->VALUES (‘localhost’,’courier’,’’);
mysql>UPDATA user SET password=password(‘haha’)
->WHERE user=’courier’;
mysql>FLUSH PRIVILEGES;
mysql>GRAN select,insert,update on mail.* TO courier;
mysql>exit
