Sendmailでauthinfoを提供すると「530認証が必要」エラーメッセージが表示される

sender_email- 存在しない電子メールアドレスですが、受信ホストが他の電子メールからの電子メールを拒否するため、送信者アドレスとして使用する必要があります。

receiver_email- メッセージを送信した電子メールを受信する必要があります。

local_smtp– ローカルネットワーク上の他のコンピュータに SMTP サーバをインストールし、すべての着信メールを次のコンピュータに転送します。external_smtp

external_smtp- 他のネットワーク上のコンピュータにSMTPサーバーをインストールし、他のネットワークから来ていないすべての電子メールを拒否します。sender_email

特定のEメールからのEメールのみを受け入れるように、Eメールをさらに転送する必要があるユーザー/パスワードでEメールを送信およびsender_email認証するようにsendmailを設定しました。この場合はそうです。ただし、ログファイルによると、認証にはsendmailが代わりに使用されます。を通じて認証したくありません。なぜならによって違うからです。local_smtpexternal_smtpsender_emailexternal_smtplocal_smtpexternal_smtplocal_smtp

関連があるようですが、どのようにAUTH=sender_email変更するのかわかりません。
