Postfix邮件系统安装手册

　　10.安装Courier-imap-1.7.1(need gmake、expect)

　　1、安装

　　hawk# pkg_add -r gmake 远程安装包

　　hawk# pw useradd cnhawk -g wheel(the software MUST run the configure script as normal user, not root)

　　hawk$ bunzip2 courier-imap-1.7.1.tar.bz2

　　hawk$ tar xvf courier-imap-1.7.1.tar

　　hawk$ cd courier-imap-1.7.1

　　如果你的mysql是源码编译请用下面这个命令

　　hawk$ ./configure --without-ipv6 --enable-unicode

　　--enable-workarounds-for-imap-client-bugs

　　--with-mysql-libs=/usr/local/mysql/lib/mysql

　　--with-mysql-includes=/usr/local/mysql/include/mysql

　　如果你的mysql是ports安装请用下面这个命令

　　Hawk$./configure --without-ipv6 --enable-unicode --enable-workarounds-for-imap-client-bugs --with-mysql-libs=/usr/local/lib/mysql --with-mysql-includes=/usr/local/include/mysql

　　hawk$ gmake

　　hawk# su root

　　hawk# gmake install
　　# 记住一定用 gmake
　　hawk# gmake install-configure

　　2)配置

　　编辑修改/usr/lib/courier-imap/etc/authmysqlrc 示例：authmysqlrc

　　##VERSION: $Id: authmysqlrc,v 1.10 2002/04/02 23:41:41 mrsam Exp $

　　#

　　# MYSQL_SOCKET can be used with MySQL version 3.22 or later, it specifies the

　　# filesystem pipe used for the connection

　　#

　　MYSQL_SOCKET /tmp/mysql.sock

　　##NAME: MYSQL_PORT:0

　　#

　　# MYSQL_PORT can be used with MySQL version 3.22 or later to specify a port to

　　MYSQL_DATABASE mail

　　##NAME: MYSQL_USER_TABLE:0

　　#

　　# The name of the table containing your user data. See README.authmysqlrc

　　# for the required fields in this table.

　　MYSQL_USER_TABLE virtual_users

　　##NAME: MYSQL_CRYPT_PWFIELD:0

　　#

　　# Either MYSQL_CRYPT_PWFIELD or MYSQL_CLEAR_PWFIELD must be defined. Both

　　# are OK too. crypted passwords go into MYSQL_CRYPT_PWFIELD, cleartext

　　# passwords go into MYSQL_CLEAR_PWFIELD. Cleartext passwords allow

　　# CRAM-MD5 authentication to be implemented.

　　MYSQL_CRYPT_PWFIELD password

　　##NAME: MYSQL_CLEAR_PWFIELD:0

　　#

　　#

　　# MYSQL_CLEAR_PWFIELD clear

　　##NAME: MYSQL_DEFAULT_DOMAIN:0

　　#

　　# If DEFAULT_DOMAIN is defined, and someone tries to log in as 'user',

　　# we will look up 'user@DEFAULT_DOMAIN' instead.

　　#

　　#

　　##NAME: MYSQL_UID_FIELD:0

　　#

　　# Other fields in the mysql table:

　　#

　　# MYSQL_UID_FIELD - contains the numerical userid of the account

　　#

　　MYSQL_UID_FIELD uid

　　##NAME: MYSQL_GID_FIELD:0

　　#

　　# Numerical groupid of the account

　　MYSQL_GID_FIELD gid

　　##NAME: MYSQL_LOGIN_FIELD:0

　　#

　　# The login id, default is id. Basically the query is:

　　#

　　# SELECT MYSQL_UID_FIELD, MYSQL_GID_FIELD, ... WHERE id='loginid'

　　#

　　MYSQL_LOGIN_FIELD id

　　##NAME: MYSQL_HOME_FIELD:0

　　#

　　MYSQL_HOME_FIELD home

　　##NAME: MYSQL_NAME_FIELD:0

　　#

　　# The user's name (optional)

　　MYSQL_NAME_FIELD name

　　##NAME: MYSQL_MAILDIR_FIELD:0

　　#

　　# This is an optional field, and can be used to specify an arbitrary

　　# location of the maildir for the account, which normally defaults to

　　# $HOME/Maildir (where $HOME is read from MYSQL_HOME_FIELD).

　　#

　　# You still need to provide a MYSQL_HOME_FIELD, even if you uncomment this

　　# out.

　　#

　　MYSQL_MAILDIR_FIELD maildir

　　##NAME: MYSQL_QUOTA_FIELD:0

　　#

　　# Define MYSQL_QUOTA_FIELD to be the name of the field that can optionally

　　# specify a maildir quota. See README.maildirquota for more information

　　#

　　MYSQL_QUOTA_FIELD quota

　　##NAME: MYSQL_WHERE_CLAUSE:0

　　#

　　# This is optional, MYSQL_WHERE_CLAUSE can be basically set to an arbitrary

　　# fixed string that is appended to the WHERE clause of our query

　　#

　　MYSQL_WHERE_CLAUSE imapok=1

　　##NAME: MYSQL_SELECT_CLAUSE:0

　　#

　　# (EXPERIMENTAL)

　　# This is optional, MYSQL_SELECT_CLAUSE can be set when you have a database,

　　# which is structuraly different from proposed. The fixed string will

　　# be used to do a SELECT operation on database, which should return fields

　　# in order specified bellow:

　　#

　　# username, cryptpw, uid, gid, clearpw, home, maildir, quota, fullname

　　#

　　# Enabling this option causes ignorance of any other field-related

　　# options, excluding default domain.

　　#

　　# There are two variables, which you can use. Substitution will be made

　　# for them, so you can put entered username (local part) and domain name

　　# in the right place of your query. These variables are:

　　# $(local_part) and $(domain)

　　#

　　# If a $(domain) is empty (not given by the remote user) the default domain

　　# name is used in its place.

　　#

　　# This example is a little bit modified adaptation of vmail-sql

　　# database scheme:

　　#

　　# MYSQL_SELECT_CLAUSE SELECT popbox.local_part,

　　# CONCAT('{MD5}', popbox.password_hash),

　　# popbox.clearpw,

　　# domain.uid,

　　# domain.gid,

　　# CONCAT(domain.path, '/', popbox.mbox_name),

　　# '',

　　# domain.quota,

　　# '',

　　# FROM popbox, domain

　　# WHERE popbox.local_part = '$(local_part)'

　　# AND popbox.domain_name = '$(domain)'

　　# AND popbox.domain_name = domain.domain_name

　　#

　　##NAME: MYSQL_CHPASS_CLAUSE:0

　　#

　　# (EXPERIMENTAL)

　　# This is optional, MYSQL_CHPASS_CLAUSE can be set when you have a database,

　　# which is structuraly different from proposed. The fixed string will

　　# be used to do an UPDATE operation on database. In other words, it is

　　# used, when changing password.

　　#

　　# There are four variables, which you can use. Substitution will be made

　　# for them, so you can put entered username (local part) and domain name

　　# in the right place of your query. There variables are:

　　# $(local_part) , $(domain) , $(newpass) , $(newpass_crypt)

　　#

　　# If a $(domain) is empty (not given by the remote user) the default domain

　　# name is used in its place.

　　# $(newpass) contains plain password

　　# $(newpass_crypt) contains its crypted form

　　#

　　# MYSQL_CHPASS_CLAUSE UPDATE popbox

　　# SET clearpw='$(newpass)',

　　# password_hash='$(newpass_crypt)'

　　# WHERE local_part='$(local_part)'

　　# AND domain_name='$(domain)'

　　#

　　编辑修改/usr/lib/courier-imap/etc/authdaemonrc

　　version="authdaemond.mysql"

　　3)设置自启动

　　hawk# cd /usr/local/etc/rc.d

　　hawk# ln -s /usr/lib/courier-imap/libexec/imapd.rc imapd.sh

　　hawk# ln -s /usr/lib/courier-imap/libexec/pop3d.rc pop3d.sh

　　hawk# chmod 755 imapd.sh

　　hawk# chmod 755 pop3d.sh

　　现在开始测试：

　　1)设置用户：

　　hawk# mysql

　　mysql> use mail;

　　在数据库里你可以看到

　　mysql> show tables;

　　+----------------+

　　| Tables_in_mail |

　　+----------------+

　　| aliases |

　　| transport |

　　| virtual_users |

　　+----------------+

　　mysql> desc aliases;

　　+-------+--------------+------+-----+---------+-------+

　　| Field | Type | Null | Key | Default | Extra |

　　+-------+--------------+------+-----+---------+-------+

　　| alias | varchar(255) | | PRI | | |

　　| rcpt | varchar(255) | YES | | NULL | |

　　+-------+--------------+------+-----+---------+-------+

　　mysql> insert aliases values('postmaster@the9.com','cnhawk@the9.com');

　　mysql> insert aliases values('postmaster@freebsd.net','cnhawk@freebsd.net');

　　mysql> select * from aliases;

　　+--------------------------+--------------------+

　　| alias | rcpt |

　　+--------------------------+--------------------+

　　| postmaster@the9.com | cnhawk@the9.com |

　　| postmaster@freebsd.net | cnhawk@freebse.net |

　　+--------------------------+--------------------+

　　mysql> desc transport;

　　+-----------+-----------+------+-----+---------+-------+

　　| Field | Type | Null | Key | Default | Extra |

　　+-----------+-----------+------+-----+---------+-------+

　　| domain | char(128) | | PRI | | |

　　| transport | char(128) | | | | |

　　+-----------+-----------+------+-----+---------+-------+

　　mysql> insert transport values('the9.com','virtual:');

　　mysql> insert transport values('freebsd.net','virtual:');

　　mysql> select * from transport;

　　+---------------+-----------+

　　| domain | transport |

　　+---------------+-----------+

　　| nankai.edu.cn | virtual: |

　　| freebsd.net | virtual: |

　　+---------------+-----------+

　　mysql> desc virtual_users;

　　+-----------+---------------------+------+-----+----------+----------------+

　　| Field | Type | Null | Key | Default | Extra |

　　+-----------+---------------------+------+-----+----------+----------------+

　　| unique_id | int(32) unsigned | | MUL | NULL | auto_increment |

　　| id | char(128) | | PRI | | |

　　| password | char(128) | YES | | NULL | |

　　| uid | int(10) unsigned | YES | | 104 | |

　　| gid | int(10) unsigned | YES | | 104 | |

　　| home | char(255) | YES | | NULL | |

　　| maildir | char(255) | YES | | NULL | |

　　| date_add | date | YES | | NULL | |

　　| time_add | time | YES | | NULL | |

　　| domain | char(128) | YES | | NULL | |

　　| name | char(255) | YES | | NULL | |

　　| imapok | tinyint(3) unsigned | YES | | 1 | |

　　| quota | char(255) | YES | | 10485760 | |

　　+-----------+---------------------+------+-----+----------+----------------+

　　mysql> INSERT INTO virtual_users

　　mysql> (id,home,password,maildir,date_add,time_add,domain,name)

　　mysql> VALUES ('cnhawk@the9.com','/var/mail/',encrypt('cnhawk'),

　　mysql> 'the9.com/cnhawk/Maildir/','2003-04-23','01:18:24','the9.com','cnhawk');

　　mysql> INSERT INTO virtual_users

　　mysql> (id,home,password,maildir,date_add,time_add,domain,name)

　　mysql> VALUES ('hawk@freebsd.net','/var/mail/',encrypt('hawk'),

　　mysql> 'freebsd.net/hawk/Maildir/','2003-04-23','01:18:24','freebsd.net','hawk');

　　mysql> quit

　　2)设置用户的目录与权限：

　　hawk# mkdir -p /var/mail/the9.com/cnhawk

　　hawk# mkdir -p /var/mail/freebsd.net/hawk

　　hawk# cd /usr/lib/courier-imap/bin

　　hawk# ./maildirmake /var/mail/the9.com/cnhawk/Maildir

　　hawk# ./maildirmake /var/mail/freebsd.net/hawk/Maildir

　　hawk# chmod -R 700 /var/mail/the9.com/

　　hawk# chmod -R 700 /var/mail/freebsd.net/

　　hawk# chown -R postfix:postfix /var/mail/the9.com

　　hawk# chown -R postfix:postfix /var/mail/freebsd.net

　　至此用户设置完毕，这里仅仅使用两个虚拟域，同理可以设置若干个虚拟域，如：mail.com

　　3)用户登录测试：

　　先用perl的mod来产生这个base64编码，安装ports在/usr/ports/converters/p5-MIME-Base64/

　　先获取plain字符窜。为了获得plain字符串，必须要用base64编码

　　hawk# perl -MMIME::Base64 -e 'print encode_base64("cnhawk@the9.com");'

　　在@前面的加个才可以成功得到字符串

　　Y25oYXdrQHRoZTkuY29t

　　hawk# perl -MMIME::Base64 -e 'print encode_base64("cnhawk");'

　　Y25oYXdr

　　也可以使用任何其它的邮件客户端程序来测试，如foxmail、Outlook Express等等。

　　然后安装webmail

　　安装igenus

　　使用修改过的版本： http://218.6.128.194/igenus_docn.tar.gz

　　1.安装：

　　hawk # cd /usr/ports/www/apache2

　　hawk # make install

　　hawk# cd /usr/ports/www/mod_php4

　　hawk# make install

　　hawk# cd /var/mail

　　hawk# tar zxvf igenus_docn.tar.gz

　　hawk# edit /usr/local/apache/conf/httpd.conf

　　2.配置：

　　1)Group nobody、User nobody

　　修改为： Group postfix、User postfix

　　2)DocumentRoot "/usr/local/apache/htdocs"

　　修改为：DocumentRoot "/var/mail/webmail"

　　3) 查找 AddDefaultCharset ISO-8859-1

　　改为AddDefaultCharset GB2312 #中文支持

　　添加AddType application/x-httpd-php .php #php支持

　　4)修改config_inc.php文件

　　$CFG_BASEPATH = "/var/mail/webmail";

　　$CFG_MYSQL_HOST = 'localhost';

　　$CFG_MYSQL_USER = 'postfix';

　　$CFG_MYSQL_PASS = 'hawk';(同以上密码，均可以自己修改)

　　$CFG_MYSQL_DB = 'mail';

　　5) 编辑/usr/local/etc/php.ini，修改：

　　Cp /usr/local/etc/php.ini-dist /usr/local/etc/php.ini

　　register_globals = On

　　3.使用：

　　最后在浏览器的URL中输入：

　　http://IP 因为没有DNS 有了DNS就好了 可以直接定位域名

　　1. 修改/etc/php.ini

　　max_execution_time = 30 #改为60 (增加处理脚本的时间限制)

　　memory_limit = 8M #改为40M (这样才能发10M的附件)

　　post_max_size = 2M #改为10M

　　upload_max_filesize = 2M #改为10M

　　2. 修改/etc/httpd/conf.d/php.conf

　　SetOutputFilter PHP

　　SetInputFilter PHP

　　LimitRequestBody 524288 #把524288改为10485760

　　这里的 LimitRequestBody 524288 限定了上传附件的上限为512k, 将其改为10M

　　3. 修改/etc/postfix/main.cf, 添加如下语句:

　　message_size_limit = 14336000

　　postfix的默认值是10M, 但这指的是邮件正文和编码后附件的总和, 经过base64编码,附件的大小会增加35%左右, 因此这里设定可接受邮件的大小为14M

　　可以使用如下命令查看postfix的有关设定:

　　/usr/sbin/postconf | grep size

　　4. 重起apache和postfix.

　　剩下反病毒反垃圾了:)
