PostfixとSendGrid「リレーアクセスが拒否されました」

私の電子メール設定は正しいようですが、まだSendGridを介して他の場所から電子メールを送信することはできません。問題はSSL設定にあると思います。これが私が見つけたものです/var/log/mail.log。

ThunderBirdを介して電子メールを送信しようとしましたが、成功しませんでした。前に述べたように、それは問題だとは思わず、SendGrid外部IPが電子メールを送信することを許可しません。サーバーから電子メールを送信すると機能します。

echo 'Test passed.' | mail -s Test-Email <email>
