試したこと

heroku logs に
Net::SMTPAuthenticationError (535 Authentication failed: account disabled
があったため、こちらを参考にheroku appの再構築。

その他、無関係かも知れないが気になる点

・railsチュートリアルを参考にしながら作業をしているのですが、チュートリアルではメールの中身が、'Content-Transfer-Encoding: 7bit'でエンコードされているのですが、私のは'Content-Transfer-Encoding: base64'になってしまっている。

何か解決策やアドバイスがあればよろしくお願いいたします。

Answer 1

Net::SMTPAuthenticationError (535 Authentication failed: account disabled

ってことですから、SMTPサーバーへの接続アカウント情報の間違いですね

回答いただきありがとうございます。

数か月前にsendgridからパスワードを強制リセットしたとのメールが来ておりました。。
ご指摘頂いた通りアカウント情報の照合が取れていないように思えます。一先ずsendgridのアカウントの復旧をしてみます。

Answer 2

・sendgridのアカウント、API_KEYの作成
・heroku configにて、作成したSENDGRID_USERNAME,SENDGRID_PASSWORD,API_KEYをセット

でメールが送れるようになりました。
