Postfix + MailManの自動化スクリプトについて - とあるサーバエンジニアの備忘録

この度PostfixにMailManを組み込んでアーカイブ機能付きメーリングリストを設定して見たが、バーチャルドメインを運用している関係上transport_mapにてローカル配送を実現させる必要がありました。

メーリングリストの作成は、WEBUIから出来るのにローカル配送を実現させるために一々SSHなりしてtransport_mapに設定したファイルを編集するのはめんどうということで以下のスクリプトを作って見ました。
※MailManをソースとかを改編すれば出来るのでないかと思いますが、Pythonを読めないので･･･

crontabに仕込んで1分置きに実行することでなんとなくリアルタイム感を出しています。

上記のスクリプトを仕込んだら、比較対象元のファイルを空で作成する。

touch /etc/mailman/virtual-mailman.OLD

1 2	touch /etc/mailman/virtual-mailman.OLD

出力先のファイルをPostfixのmain.cfに指定する。

transport_maps = hash:/etc/postfix/transport, hash:/etc/mailman/maillist

1 2	transport_maps = hash:/etc/postfix/transport, hash:/etc/mailman/maillist

こんな感じの内容で作成される。
