私は次の手順に従って、VPS 上にメール サーバーをセットアップしました。https://www.linuxbabe.com/mail-server/centos-8-iredmail-email-server
インストールが正常に完了した後、自分の Web サイト アドレス (sssss.com例) にアクセスすると、自動的にリダイレクトされsssss.com/mail、電子メール ログイン ページが表示されます。そのため、Web サイトの最初のページにアクセスできません。
以下は私の VPS 上の関連ファイルです。

- If you are building an AUTHORITATIVE DNS server, do NOT enable recursion.
- If you are building a RECURSIVE (caching) DNS server, you need to enable
recursion.
- If your recursive DNS server has a public IP address, you MUST enable access
control to limit queries to your legitimate users. Failing to do so will
cause your server to become part of large scale DNS amplification
attacks. Implementing BCP38 within your network would greatly
reduce such attack surface
