Postfixによるメールサーバ構築 (Postfix+MySQL+Dovecot+postfixadmin)

Dovecotのインストール

yum -y install dovecot
chkconfig dovecot on
chkconfig --list dovecot

Dovecotの設定

cp /etc/dovecot.conf /etc/dovecot.conf.org
vi /etc/dovecot.conf
-------------------------------------------------------------------------------
#protocols = imap imaps pop3 pop3s
protocols = pop3 imap
mail_location = maildir:/mail/%d/%u

#passdb pam {
#}
passdb sql {
args = /etc/dovecot-mysql.conf
}
#userdb passwd {
#}
userdb sql {
args = /etc/dovecot-mysql.conf
}
#mechanisms = plain
mechanisms = plain login digest-md5 cram-md5

login_process_size = 64
-------------------------------------------------------------------------------

cat < /etc/dovecot-mysql.conf
driver = mysql
default_pass_scheme = PLAIN
connect = dbname=postfix user=postfix host=/var/lib/mysql/mysql.sock password=Lr9WNUJK
password_query = SELECT password FROM mailbox WHERE username = '%u' AND active = '1'
user_query = SELECT concat('/mail/', maildir) as home, 10000 as uid, 10000 as gid FROM mailbox WHERE username = '%u' AND active = '1'
EOF

認証のライブラリをインストール

yum -y install cyrus-sasl-plain cyrus-sasl-md5

saslauthdは利用しないので念のため停止しておきます。停止時にFAILEDなどがでても大丈夫です。

/etc/rc.d/init.d/saslauthd stop
chkconfig saslauthd off

Postfix Dovecotの起動

PostfixとDovecotの起動を行って設定完了です。/var/log/maillogにエラーなどがでていないか確認してください。

/etc/init.d/dovecot start
/etc/init.d/postfix start
