こんにちは。ちゃぼP（@chabo0429）です。
さて、IMAPサーバの箱はできたので、後はSSHから手動設定を進めてゆく。
まず、ReadyNASではsendmailではなく、Postfixを使う。

Postfixの設定
Postfixはすでにインストールされているので、まずは「main.cf」の編集。

としてみる。
このバージョンではsslやSMTP認証をサポートしていないのか、設定を入れてもまともに動いてくれなかった。
とはいえ、外部からのメールも問題なし。不正中継サーバとしてチェックもしたがすべて合格。とりあえずは踏み台にはならない設定になっているようだ。
LAN内からの送信もOK。外部からリモートで送信するには、VPNでログインして送信するか、WEBメールを使用すればよいだろうということにした。
次回は、WEBメールを設定していこう。
