コンテキスト：ローカルプライベートネットワークでRaspberry Piを使用しています。 cronが私にEメールを送信したいのですが、最後のEメールを送信すると次のエラーが発生します。このエラーを確認するには、mailq次のコマンドを使用しました。
(delivery temporarily suspended: SASL authentication failed; cannot authenticate to server smtp.gmail.com[75.124.190.102]: no mechanism available)
[email protected]
何が間違っている可能性がありますか？ /etc/postfix/sasl_passwd ファイルを次のように設定しました。
[smtp.gmail.com]:587 [email protected]:myPassword
これは私の/etc/postfix/main.cfファイルです。
