Postfix

環境

CentOS6

事前インストール

Postfixadmin 構築手順

# cp -p /etc/postfix/main.cf /etc/postfix/main.cf.`date +%Y%m%d`
# vi /etc/postfix/main.cf 
myhostname = mail01.example.jp 
mydomain = example.jp
myorigin = $mydomain
inet_interfaces = all
mynetworks = 127.0.0.0/8, [::1]/128
home_mailbox = Maildir/
smtpd_banner = ESMTP unknown

smtpd_sasl_auth_enable = yes
smtpd_sasl_local_domain = $mydomain
smtpd_recipient_restrictions =
      reject_unauth_destination,
      permit_mynetworks,                                 <-- localhostからも認証必須にする場合は削除する
      permit_sasl_authenticated

broken_sasl_auth_clients=yes

smtpd_client_restrictions =
        permit_mynetworks,
        reject_rbl_client all.rbl.jp,
      #  reject_rbl_client list.dsbl.org,
        reject_rbl_client bl.spamcop.net,
        reject_rbl_client relays.ordb.org,
        reject_rbl_client sbl-xbl.spamhaus.org

### clamav
#smtpd_milters = unix:/var/run/clamav/clamav-milter.sock
#non_smtpd_milters = unix:/var/run/clamav/clamav-milter.sock
#milter_default_action = accept

### Postfix admin settings

#  -o smtpd_enforce_tls=yes
  -o smtpd_sasl_auth_enable=yes
  -o smtpd_client_restrictions=permit_sasl_authenticated,reject

バーチャルドメイン用のユーザとグループを作成

# groupadd -g 5000 mailuser
# useradd -u 5000 -g 5000 -d /home/mailuser -s /sbin/nologin mailuser

postfixのsmtp-auth mysql設定

# cp -p /etc/sasl2/smtpd.conf /etc/sasl2/smtpd.conf.`date +%Y%m%d`
# vi /etc/sasl2/smtpd.conf 
# smtpd.conf
pwcheck_method: auxprop
auxprop_plugin: sql
allowplaintext: yes
mech_list: plain login

sql_engine: mysql
sql_hostnames: localhost
sql_user: postfixuser
sql_passwd: EX@mpLEP@ss2013
sql_database: postfix
sql_select: SELECT password FROM mailbox WHERE username = '%u@%r' AND active = '1'

Postfixadminのインストールと設定

ユーザ情報登録用のデータベースを作成

# mysql -u root -p 
mysql> CREATE DATABASE postfix
mysql> GRANT ALL PRIVILEGES ON postfix.* TO postfixuser@localhost IDENTIFIED BY 'EX@mpLEP@ss2013';

Postixadminの取得と設置

※postfixadminは最新版を取得すること

# wget "http://downloads.sourceforge.net/project/postfixadmin/postfixadmin/postfixadmin-2.3.5/postfixadmin-2.3.5.tar.gz?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fpostfixadmin%2F&ts=1343955693&use_mirror=jaist"
# tar xzvf postfixadmin-2.3.5.tar.gz
# mv postfixadmin-2.3.5 /var/www/vhosts/mailmaster
 

Postixadmin初期設定

# cp -p /var/www/vhosts/mailmaster/config.inc.php /var/www/vhosts/mailmaster/config.inc.php.`date +%Y%m%d`
# vi /var/www/vhosts/mailmaster/config.inc.php
[変更箇所]
$CONF['configured'] = true;
$CONF['setup_password'] = 'changeme'; ←今は未記入のままでOK
$CONF['default_language'] = 'ja';
$CONF['postfix_admin_url'] = 'http://www.example.jp/mailmaster';

//Database Config
$CONF['database_user'] = 'postfixuser';
$CONF['database_password'] = 'EX@mpLEP@ss2013';
$CONF['database_name'] = 'postfix';

$CONF['admin_email'] = 'postmaster@example.jp'; 
$CONF['encrypt'] = 'cleartext';

$CONF['page_size'] = '100'

$CONF['domain_path'] = 'YES';

$CONF['aliases'] = '300';
$CONF['mailboxes'] = '500';
$CONF['maxquota'] = '500';

ブラウザでhttp://xxx/mailmaster/setup.phpにアクセスする。

「Setup password」を入力してsubmitすると、 
$CONF['setup_password'] = ‘aa45fgasfgkldhfahsldhf2asjdqweroajsdfasdfasd’; 
のようなパラメータが赤字で表示されるので、config.inc.phpに反映させる。

# vi /var/www/vhosts/mailmaster/config.inc.php
[再修正]
$CONF['setup_password'] = 'changeme';

再度ブラウザでhttp://xxx/mailmaster/setup.phpにアクセスする。

再度setup.phpにアクセスして管理者(特権管理者となる)を登録する。
index.phpにアクセスするとログイン画面が表示されるので、 登録した管理者でログインする。
引き続きドメインの設定、ユーザの設定を行うとユーザ情報用のデータベースに以下のようなレコードが登録されている。
