Dovecotとpostfixを構成しました...電子メールサーバーは正常に動作します。(WebmailとOutlookはどちらも機能します。)unixコマンドを使用してユーザーを作成しました..
usreadd -s /sbin/nologin myuser
しかし、懸念があります。WebメールまたはOutlookにログインする場合、myuser @ mydomain.comではなくmyuserを使用する必要があります。
とりあえず使っているのは以下のユーザー名のみ。
[email protected]を使用すると、WebメールとOutlookの両方が無効なユーザーであると表示されます。
私はグーグルを試してみました..運が悪い.. ..親切に誰かが光を当ててください..

10-auth.confを編集してauth_username_formatのコメントを外し、%nを追加するだけで問題が解決しました。
