私はキーコードを電子メールで送信しようとしていますが、毎回このエラーが発生します: - "サーバーが送信者アドレスを拒否しました。サーバー応答:530 5.7.0最初にSTARTTLSコマンドを発行する必要があります。 e6sm29167643pfj.71 - gsmtp。 "となります。私は問題がSendMails()であると思うが、その問題は何か分かっていない。私を助けてください。私はVisual studio community 2015を使用していますか?エラー: - サーバーが送信者アドレスを拒否しました。サーバーの応答は:530 5.7.0最初にSTARTTLSコマンドを発行する必要があります。 e6sm29167643pfj.71 - gsmtp
