戯れの日々: dovecotインストール

LDAPを設定する機会にあわせて、dovecot-2.0.17-1をインストールする。いつもは、POP3をインストールするが、昨今の Thin client化の波やオフィスや出先の（別の端末からメール確認）を考えてIMAPである dovecot-2.0.16-1をインストールすることにした。パッケージのインストールには、unixlife.repo にお世話になりました。
LDAP + DOVECOT2

dovecotの概要
Dovecotは、デフォルトでPOP3とIMAPが動作するように設定されていますが、Courie-IMAPと同様にPOP3sとIMAPsもサポートされています。

今回は、dovecotをIMAP4とPOP3をクライアントが選択できるように設定します。

設定内容もほぼ標準で問題ないようだ。
■dovecotの設定内容の確認
doveconf -a　（同じ dovecot -a ）
設定内容を表示する。（コメントが除去されてすべての設定内容が表示される。）
doveconf -n
標準設定以外の設定項目を出力する。
他にもオプションはあるが、manコマンドで確認して下さい。
