erro no envio do correio para a excepção smtp?
StringBuilder emailMessage = new StringBuilder();
emailMessage.Append("Dear Payment Team ,");
emailMessage.Append("<br><br>Please find the Payment instruction");
try
{
MailMessage Msg = new MailMessage();
// Sender e-mail address.
Msg.From = new MailAddress("[email protected]");
// Recipient e-mail address.
Msg.To.Add("[email protected]");
Msg.CC.Add("[email protected]");
Msg.Subject = "Timesheet Payment Instruction updated";
Msg.IsBodyHtml = true;
Msg.Body = emailMessage.ToString();
SmtpClient smtp = new SmtpClient();
//smtp.EnableSsl = true;
smtp.Host = ConfigurationManager.AppSettings["HostName"];
smtp.Port = int.Parse(ConfigurationManager.AppSettings["PortNumber"]);
smtp.Send(Msg);
Msg = null;
Page.RegisterStartupScript("UserMsg", "<script>alert('Mail has been sent successfully.')</script>");
}
catch (Exception ex)
{
Console.WriteLine("{0} Exception caught.", ex);
}
adicionei este código na web.config
<appSettings>
<add key="HostName" value="The host name as given by my company" />
<add key="PortNumber" value="25" />
</appSettings>
continuo a ter uma excepção, tentei mudar o número do porto como especificado, mas sem sucesso

Tem de dar o nome de Utilizador e a senha para o smtp.
Utilizar o código abaixo: -
MailSettings.SMTPServer = Convert.ToString(ConfigurationManager.AppSettings["HostName"]);
MailMessage Msg = new MailMessage();
// Sender e-mail address.
Msg.From = new MailAddress("[email protected]");
// Recipient e-mail address.
Msg.To.Add("[email protected]");
Msg.CC.Add("[email protected]");
Msg.Subject = "Timesheet Payment Instruction updated";
Msg.IsBodyHtml = true;
Msg.Body = emailMessage.ToString();
NetworkCredential loginInfo = new NetworkCredential(Convert.ToString(ConfigurationManager.AppSettings["UserName"]), Convert.ToString(ConfigurationManager.AppSettings["Password"])); // password for connection smtp if u dont have have then pass blank
SmtpClient smtp = new SmtpClient();
smtp.UseDefaultCredentials = true;
smtp.Credentials = loginInfo;
//smtp.EnableSsl = true;
//No need for port
//smtp.Host = ConfigurationManager.AppSettings["HostName"];
//smtp.Port = int.Parse(ConfigurationManager.AppSettings["PortNumber"]);
smtp.Send(Msg);

Primeiro, você não precisa ler manualmente os valores no seu .ficheiro de configuração. Você pode definir o System.Net a secção e o seu objecto SmtpClient Irão lê-los automaticamente:
<system.net>
<mailSettings>
<smtp from="Sender's display name <[email protected]>">
<network host="mailserver.yourdomain.com" port="25" userName="smtp_server_username" password="secret" defaultCredentials="false" />
</smtp>
</mailSettings>
</system.net>
Então, a partir do seu código, basta escrever:
SmtpClient smtp = new SmtpClient();
MailMessage mailMessage = new MailMessage();
mailMessage.To.Add(new MailAddress("[email protected]", "Recipient Display Name"));
mailMessage.Subject = "Some Subject";
mailMessage.Body = "One gorgeous body";
smtp.Send(mailMessage);
Voltando ao seu erro, parece que tem algum tipo de problema de rede.

Sugiro que seja a forma mais simples de enviar e - mails com excepção, usando o Elmah. Por favor, siga esta linha de orientação para a solução:

Outra razão para esta excepção pode ser o vírus anti instalado no seu sistema. Isto pode estar proibindo a aplicação para enviar e-mails. Basta olhar para fora para uma caixa de diálogo que está pedindo permissão para enviar e-mails através de uma aplicação em seu sistema.
