Django 1.8とPleskで電子メール送信者を設定する際の問題

Django 1.8とPleskを使用してWebサイトを設定しようとしていて、電子メール変数を任意の値に設定しようとすると、 Gmailとメールサーバーをホストから試しましたが、エラーは同じです。私はPythonのsmtplibをテストし、それを介して電子メールを送信したので、DjangoとPleskの間にあるかもしれないようです。テスト用のCentOS 6サーバーでWebサイトを設定しても、この問題は発生しません。Django 1.8とPleskで電子メール送信者を設定する際の問題

例Configが

EMAIL_HOST = "smtp.gmail.com" 
EMAIL_HOST_PASSWORD = "mypassword" 
EMAIL_HOST_USER = "[email protected]" 
EMAIL_PORT = 587
