Postfixを使ったメールサーバ構築.3/postfixの設定

さて、少し時間が空きましたが、postfixの設定について書いていきます。
まずは、”/etc/postfix/main.cf”から。

なお、修正したところ、コメントを外したところ、などを記述しています。
この設定をそのままコピーペーストすればいい、という性質のものではありません。

次に”/etc/postfix/master.cf”です。
こちらも同様に修正が必要な部分、追加が必要な部分のみを記述しています。
[bash]

続いて、mysqlからいろいろなデータを呼び出すためのconfファイルです。
全部で5本あります。
[bash]
[root@xxxx postfix]# vi /etc/postfix/mysql-relay_domains_maps.cf
hosts = localhost
user = postfix
password = mysqlのpostfixユーザパスワードを記述
dbname = postfix
query = SELECT domain FROM domain WHERE domain=’%s’ AND backupmx = ‘1’
[root@xxxx postfix]# vi /etc/postfix/mysql-virtual_alias_maps.cf
hosts = localhost
user = postfix
password = mysqlのpostfixユーザパスワードを記述
dbname = postfix
query = SELECT goto FROM alias WHERE address=’%s’ AND active = ‘1’
[root@xxxx postfix]# vi /etc/postfix/mysql-virtual_domains_maps.cf
hosts = localhost
user = postfix
password = mysqlのpostfixユーザパスワードを記述
dbname = postfix
query = SELECT domain FROM domain WHERE domain=’%s’ AND backupmx = ‘0’ AND active = ‘1’
[root@xxxx postfix]# vi /etc/postfix/mysql-virtual_mailbox_limit_maps.cf
hosts = localhost
user = postfix
password = mysqlのpostfixユーザパスワードを記述
dbname = postfix
query = SELECT quota FROM mailbox WHERE username=’%s’ AND active = ‘1’
[root@xxxx postfix]# vi /etc/postfix/mysql-virtual_mailbox_maps.cf
hosts = localhost
user = postfix
password = mysqlのpostfixユーザパスワードを記述
dbname = postfix
query = SELECT maildir FROM mailbox WHERE username=’%s’ AND active = ‘1’
[/bash]
次回はpostfixadminの設定について書いていきましょう。
