一、      简介

详细见官方文档

http://wiki.extmail.org/extmail_solution_for_linux

1 、   AM ----apache+mysql

2 、   Postfix �C mta 邮件系统

3 、   Courier-authlib-- 个为 courier-imap ， maildrop ， sasl2 提供用户信息的后台进程序

4 、   Courier-imap �C提供 pop3 服务

5 、   extmail －－一个著名的 webmail 程序

6 、   extman －－与 extmail 集成的后台管理程序

二、  安装

2.1、配置yum安装源

Vi etc/yum.repos.d/Mail-Base.repo

# Mail-Base.repo # Created by ExtMail Dev Team: http://www.extmail.org/ # $Id$ [EMOS-base] name=EMOS-Base baseurl=http://mirror.extmail.org/yum/emos/1.4/os/$basearch/ gpgcheck=0 priority=0 protect=0 [EMOS-update] name=EMOS-Updates baseurl=http://mirror.extmail.org/yum/emos/1.4/updates/$basearch/ gpgcheck=0 priority=0 protect=0

更新yum 源

Yum clean all

Yum list

2.2、postfix安装

# export RPMS=/usr/src/redhat/RPMS
# export SOURCE=/usr/src/redhat/SOURCES
# export SPEC=/usr/src/redhat/SPECS
# wget http://ftp.wl0.org/official/2.5/SRPMS/postfix-2.5.4-2.src.rpm
# rpm -ivh postfix-2.5.4-2.src.rpm

下载

创建 rpm

# cd $SPEC

修改下面选项

%define distribution rhel-5.0 %define with_mysql_redhat 1 %define with_sasl         2 %define with_vda         1

 

# rpmbuild -bb postfix.spec

# cd $RPMS/i386

# rpm -ivh postfix-2.5.4-2.rhel4.i386.rpm

切换mta

# alternatives --config mta （选择 2 ， postfix ）

# rpm -e sendmail

# cd /usr/sbin/

# mv sendmail sendmail.bak

# newaliases

# ln -s sendmail.postfix sendmail

配置postfix

# cd /etc/postfix/

# mv main.cf main.cf.bak

# vim main.cf

输入下面的内容：

queue_directory = /var/spool/postfix

command_directory = /usr/sbin

daemon_directory = /usr/libexec/postfix

data_directory = /var/lib/postfix

mail_owner = postfix

unknown_local_recipient_reject_code = 550

debug_peer_level = 2

debugger_command =

PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin

ddd $daemon_directory/$process_name $process_id & sleep 5

sendmail_path = /usr/sbin/sendmail.postfix

newaliases_path = /usr/bin/newaliases.postfix

mailq_path = /usr/bin/mailq.postfix

setgid_group = postdrop

html_directory = /usr/share/doc/postfix-2.5.2-documentation/html

manpage_directory = /usr/share/man

sample_directory = /etc/postfix

readme_directory = /usr/share/doc/postfix-2.5.2-documentation/readme

alias_database = hash:/etc/postfix/aliases

alias_maps = hash:/etc/postfix/aliases

myhostname = mail.test.com

mydomain = test.com

mydestination = $myhostname

smtpd_banner = test.com ESMTP Mail System

message_size_limit = 14680064

virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf

virtual_mailbox_base = /home/data/domains

virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf

virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf

virtual_mailbox_limit_maps = mysql:/etc/postfix/mysql_virtual_limit_maps.cf

virtual_transport = maildrop:

maildrop_destination_recipient_limit = 1

#sasl

smtpd_sasl_auth_enable = yes

smtpd_sasl2_auth_enable = yes

smtpd_sasl_security_options = noanonymous

broken_sasl_auth_clients = yes

smtpd_recipient_restrictions =

 permit_mynetworks,

 permit_sasl_authenticated,

 reject_unauth_destination,

 reject_unauth_pipelining,

 reject_invalid_hostname

2.3、安装Courier-Authlib

安装以下软件包:

# yum install courier-authlib

# yum install courier-authlib-mysql

编辑 /etc/authlib/authmysqlrc 文件 :

# vi /etc/authlib/authmysqlrc

并将其内容清空，然后增加如下内容 :

MYSQL_SERVER            localhost

MYSQL_USERNAME          extmail

MYSQL_PASSWORD          extmail

MYSQL_SOCKET            /var/lib/mysql/mysql.sock

MYSQL_PORT              3306

MYSQL_OPT               0

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)'

修改authdaemonrc 文件

# vi /etc/authlib/authdaemonrc

修改如下内容 :

authmodulelist="authmysql"

authmodulelistorig="authmysql"

如一切正常，命令行将返回如下信息：

Starting Courier authentication services: authdaemond

修改 authdaemon socket 目录权限

如果该目录权限不正确修改， maildrop 及 postfix 等将无法正确获取用户的信息及密码认证：

# chmod 755 /var/spool/authdaemon/

2.4、安装maildrop

# yum install maildrop

maildrop RPM 包安装时，会自动创建 vuser 用户及 vgroup 用户组，专门用于邮件的存储

配置 master.cf 为了使 Postfix 支持 Maildrop ，必须修改 /etc/postfix/master.cf 文件，注释掉原来的 maildrop 的配置内容，并改为：

 

maildrop   unix        -       n        n        -        -        pipe   flags=DRhu user=vuser argv=maildrop -w 90 -d ${user}@${nexthop} ${recipient} ${user} ${extension} {nexthop}

配置 main.cf 由于 maildrop 不支持一次接收多个收件人，因此必须在 main.cf 里增加如下参数：

maildrop_destination_recipient_limit = 1
