Eric's linux and nginx!

         Postfix 是一种电子邮件服务器，它是由任职于IBM华生研究中心（T.J. Watson Research Center）的荷兰籍研究员Wietse Venema为了改良sendmail邮件服务器而产生的。最早在1990年代晚期出现，是一个开放源代码的软件。
我是安装在了ubuntu server 上安装的，因为需要web界面操作,所以需要安装 apache+php
我的环境是:
ubuntu + apache2 + php5 + dovecot + postfix + postfixadmin
安装步骤:
1.首先在域名服务商的 DNS解析上添加
MX 映射： IN MX 10 mail.ludy.com.
mail IN A “IP地址”
2.安装mysql 由于我比较懒，我就用了懒人模式,安装时候要记得root 密码

Shell $> apt-get install mysql-server

创建postfix数据库，以及操作数据库user

Shell $> mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 58
Server version: 5.0.67-0ubuntu6 (Ubuntu)
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql> create database postfix;
Query OK, 1 row affected (0.00 sec)
mysql> grant all privileges on postfix.* to 'postfix'@'localhost' identified by '123456' with grant option;
Query OK, 0 rows affected (0.00 sec)
mysql> quit
Bye

3.编译安装 postfix 支持 mysql 和 dovecot

shell $>wget http://www.postfix.cn/source/official/postfix-2.6.5.tar.gz
shell $> apt-get install libmysqlclient15-dev
shell $> tar zxvf postfix-2.6.5.tar.gz
shell $> cd postfix
shell $> make tidy
shell $>make -f Makefile.init makefiles 'CCARGS=-DHAS_MYSQL -I/usr/include/mysql -DUSE_SASL_AUTH -BDEF_SERVER_SASL_TYPE=\"dovecot\"' 'AUXLIBS=-L/usr/lib/mysql -lmysqlclient -lz -lm'
shell $> make
shell $>make install

##默认main.cf 配制文件

shell $>postconf -n
command_directory = /usr/sbin
config_directory = /etc/postfix
daemon_directory = /usr/libexec/postfix
data_directory = /var/lib/postfix
debug_peer_level = 2
html_directory = no
mail_owner = postfix
mailq_path = /usr/bin/mailq
manpage_directory = /usr/local/man
newaliases_path = /usr/bin/newaliases
queue_directory = /var/spool/postfix
readme_directory = no
sample_directory = /etc/postfix
sendmail_path = /usr/sbin/sendmail
setgid_group = postdrop
unknown_local_recipient_reject_code = 550

####配份main.cf 配置文件

Shell $> mv main.cf main.cf.bak

####创建新的 main.cfg

shell $> vim main.cf
command_directory = /usr/sbin
config_directory = /etc/postfix
daemon_directory = /usr/libexec/postfix
data_directory = /var/lib/postfix
debug_peer_level = 2
html_directory = no
mail_owner = postfix
mailq_path = /usr/bin/mailq
manpage_directory = /usr/local/man
newaliases_path = /usr/bin/newaliases
queue_directory = /var/spool/postfix
readme_directory = no
sample_directory = /etc/postfix
sendmail_path = /usr/sbin/sendmail
setgid_group = postdrop
unknown_local_recipient_reject_code = 550

###创建 mysql 通信文件

shell$> cd /etc/postfix
shell $> mkdir mysql
shell $> cd mysql
shell $> vim mysql_virtual_alias_maps.cf
user = portfix
password = 123456
hosts = localhost
dbname = postfix
table = alias
select_field = goto
where_field = address

shell $> vim mysql_virtual_domains_maps.cf
user = portfix
password = 123456
hosts = localhost
dbname = postfix
table = domain
select_field = domain
where_field = domain

shell $> vim mysql_virtual_mailbox_maps.cf
user = portfix
password = 123456
hosts = localhost
dbname = postfix
table = mailbox
select_field = maildir
where_field = username

shell $> vim mysql_virtual_mailbox_limit_maps.cf
user = portfix
password = 123456
hosts = localhost
dbname = postfix
table = mailbox
select_field = quota
where_field = username

4.安装配置 dovecot-pop3d

shell $> apt-get install dovecot-pop3d
shell $> cd /etc/dovecot
shell $> mv dovecot.conf dovecot.conf.bak ##备份原有dovecot配置文件
shell $> vim dovecot.conf ## 创建新的 dovecot 配置文件
base_dir = /var/run/dovecot/
protocols = pop3 pop3s
listen = *
disable_plaintext_auth = no
log_path = /var/log/dovecot.log
info_log_path = /var/log/dovecot.info
log_timestamp = "%Y-%m-%d %H:%M:%S "
ssl_disable = yes
mail_location = maildir:/var/vmail/%u
mail_privileged_group = mail
first_valid_uid = 33
protocol imap {
}
protocol pop3 {
pop3_uidl_format = %08Xu%08Xv
}
auth default {
mechanisms = plain login
passdb pam {
}
passdb sql {
args = /etc/dovecot/dovecot-sql.conf
}
userdb passwd {
}

userdb sql {
args = /etc/dovecot/dovecot-sql.conf
}

user = root
socket listen {
client {
path = /var/spool/postfix/private/auth-client ###这里对应postfix smtpd_sasl_path
mode = 0660
user = postfix
group = postfix
}
}
}

######备份 dovecot 连接数据库配置文件

shell $> mv dovecot-sql.conf dovecot-sql.conf.bak
shell $> vim dovecot-sql.conf
driver = mysql
connect = host=localhost dbname=postfix user=postfix password=123456
default_pass_scheme = MD5-CRYPT
### 这里修改为 MD5-CRYPT 是为了与 postfixadmin 想符合，不然验证不过去总提示密码错误！

password_query = SELECT password FROM mailbox WHERE username = '%u'
user_query = SELECT maildir, 33 AS uid, 33 AS gid FROM mailbox WHERE username = '%u'

####重新启动 dovecot 服务`

shell $> /etc/init.d/dovecot restart

5. 建立 postfix 虚拟用户目录

shell $> mkdir -p /var/vmail

## 赋给 apache 权限~~~

shell $> chown www-data:www-data /var/vmail -R

6.安装配置 postfixadmin

shell $> wget 'http://downloads.sourceforge.net/project/postfixadmin/postfixadmin/postfixadmin_2.3.tar.gz?use_mirror=cdnetworks-kr-2'
shell $> tar zxvf  postfixadmin_2.3.tar.gz
shell $> mv postfixadmin-2.3 /var/www/postfixadmin
shell $> cd /var/www/postfixadmin
shell $> vim config.inc.php
#### 查找 $CONF['configured'] = false; ###
改为
$CONF['configured'] = true;
###查找  $CONF['default_language'] = 'en'; ##
改为：
$CONF['default_language'] = 'cn';
####查找
$CONF['database_type'] = 'mysql';
$CONF['database_host'] = 'localhost';
$CONF['database_user'] = 'postfix';
$CONF['database_password'] = 'postfixadmin';
$CONF['database_name'] = 'postfix';
$CONF['database_prefix'] = '';
改为：
$CONF['database_type'] = 'mysql';
$CONF['database_host'] = 'localhost';
$CONF['database_user'] = 'postfix';
$CONF['database_password'] = '123456';
$CONF['database_name'] = 'postfix';
$CONF['database_prefix'] = '';
