私はウェブアプリケーションを開発しています。
すべての送信メールはスパムとしてマークされるか、受信者のメール プロバイダーによって完全に拒否されます。
これにより、ウェルカム メール、アクティベーション コード、またはその他のものを登録ユーザーに送信できなくなります。
isnotspam.com でメール送信をテストしましたが、BAYES_99 および BAYES_999 メトリックに問題があるようです。これは、電子メールの内容に関係なく発生します。
なぜこれが起こっているのか誰か教えてもらえますか？スパム フィルターによってスパムとしてマークされていない送信メールを作成する方法はありますか?
これは isnotspam.com のテスト結果です (プライバシーのためにいくつかのパラメーターを変更しました)。
