Мое приложение размещено на IIS, запущенном на окнах 2008R2.Код для отправки почты указан ниже.Не удается отправить почту из приложения asp.net (framework версии 4), размещенного в IIS, запущенного в Windows 2008R2?

Как вы можете видеть из кода, я проверил все порты, которые используются для отправки почты. Этот же код работает с приложением, размещенным на окнах 7/8, но не работает в Windows 2008R2. Ниже приводится сообщение об ошибке я получаю
SendMail SmtpException, CertificateBypassed: Ложные SSLEnabled: Ложные smtpClient.DeliveryMethod: Сеть smtpClient.EnableSsl: Ложные smtpClient.Host:SMTP.GMAIL.COM smtpClient.Port: 587 smtpClient.UseDefaultCredentials: Ложные StatusCode: GeneralFailure
Ничто в innerexception.This же сообщение повторяется для всех ports.I посылаю это письмо через gmail.I've протестирована с MS Outlook на сервере с той же учетной записи GMAIL, и он работал правильно, поэтому я думаю, что ограничение брандмауэра - это n ot применимо в моем случае. Я также включил «Доступ для менее безопасного приложения» в настройках gmail.
