Estou usando o windows server 2008 r2 e o IIS 7.5 normalmente. Eu estou usando o IIS 6 smpt server para enviar e-mails. Agora, quando eu enviar e-mail através do meu aplicativo c # eu estou vendo 2 recebidos de cabeçalhos. Qual pode ser a causa disso?
Exibindo os cabeçalhos do Gmail e do Hotmail

Se você verificar, verá que há 2 recebidos dos cabeçalhos. Deixe-me também mostrar como eu envio e-mail e minha configuração do servidor smtp
É assim que eu envio e-mail C #
MailMessage mail = new MailMessage();
mail.To.Add(srEmail);
mail.From = new MailAddress("[email protected]", srSender);
mail.Subject = srEmailTitle;
mail.Body = srEmailBody;
mail.IsBodyHtml = true;
mail.SubjectEncoding = System.Text.Encoding.UTF8;
mail.BodyEncoding = System.Text.Encoding.UTF8;
SmtpClient smtp = new SmtpClient();
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.UseDefaultCredentials = true;
smtp.Host = "127.0.0.1";
smtp.Port = 25;
smtp.Send(mail);
Esta é a configuração do servidor IIS
Muito obrigado pela ajuda
Você recebe um cabeçalho Received para cada servidor SMTP que manipula sua mensagem. No seu caso, você obtém um quando seu aplicativo se conecta via SMTP ao host local e injeta a mensagem pela primeira vez, e um segundo cabeçalho quando esse sistema IIS passa o email para o servidor para Hotmail ou GMail.
Isso é absolutamente normal e esperado.
