なんらかの理由で数万通単位でキューにメッセージがつまってしまった場合どうするか。 まずなにより最初にすべきことは、メールサーバの停止。原因がなんであれ、万単位でキューにたまっているなら、いったん止めなければ復旧作業もままならない。おそらくキューから大量のメッセージを削除することになるだろうし、Postfixはメッセージの状態に応じて、ファイルをあちこちのディレクトリに移動させるため、その際には激しいディスクアクセスをともなう。ゆえに、mailq1つ実行するのにもディスクに足を取られて、作業にならない。同じサーバでvirus scannerなんぞが動いていたら目も当てられないくらい動作に影響がでているはず。もちろん、相応のディスクを持っていてそんなの平気なら、止めずに作業ができるかもしれない。でもふつーは無理だと思った方がいい。サービスの停止に躊躇するかもしれないけれど、いずれにせよ大幅なメ

Postfixでの複数ドメインの管理
フレッツADSLでダイナミックDNSを用いて独自ドメインを運営していますが、 持っていたドメインがいくつかあるのでそれらを一台のPCで管理しています。 Webに関しては昨日のApacheのVirtualHost機能を利用して、http://www.shioji.jp/ へのアクセス、http://www.touya.jp/へのアクセスを分けて表示するように 設定しています。 このPC自体はもともとclare.shioji.jpというホスト名にしてあり、以前にも 書いたようにlocalでのmailの配送はすでに動いています。 今回は同じPCでhoge@touya.jpあてのmailも受け取るようにします。 Postfixで複数ドメインを管理するにはvirtualというfileに管理するドメインを 書く必要があります。 Debianの場合は/etc/postfix/virtualにあり、現在は
