javamail api を使用して自動送信メール Java プロジェクトを作成しています。smtp.gmail.com ホストを使用してこのメ​​ールを送信すると、機能します。しかし、自分のホスト サーバー mail.sitename.com を使用すると、例外が表示されます。ユーザー名とパスワードは正しいです。この問題を解決するために誰か助けてください...例外は:-

さまざまなクライアント マシンで生成される可能性のあるテスト結果を含む添付ファイル付きの電子メールを送信する必要があるプロジェクトでは、次のプロパティとコードを使用しました (プロパティは、コードで言及されている設定オブジェクトのフィールドに変換されます)。下）

==================== Properties Section ====================
! Default Properties for the Email section of the project - others omitted

! The email provider may or may not require authentication - make sure to make the appropriate choices on the client
EmailSender = aUser@gmail.com
EmailPassword = unEncriptedPassword
EmailRecipients = me@gmail.com,she@gmail.com,you@yahoo.com,andAnyBodyElse@aol.com
EmailHost = smtp.gmail.com
