Added this code in web.config
<appSettings>
<add key="HostName" value="The host name as given by my company" />
<add key="PortNumber" value="25" />
</appSettings>
I keep getting an exception tried changing the port number as specified but no success

Thank you for visiting the Q&A section on Magenaut. Please note that all the answers may not help you solve the issue immediately. So please treat them as advisements. If you found the post helpful (or not), leave a comment & I’ll get back to you as soon as possible.
Method 1
You need to give Username and password for smtp.
Use Below code :-
MailSettings.SMTPServer = Convert.ToString(ConfigurationManager.AppSettings["HostName"]);
MailMessage Msg = new MailMessage();
// Sender e-mail address.
Msg.From = new MailAddress("<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="6010111220070d01090c4e030f0d">[email protected]</a>");
// Recipient e-mail address.
Msg.To.Add("<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="a5c4c7c6e5c2c8c4ccc98bc6cac8">[email protected]</a>");
Msg.CC.Add("<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="d5afb6b195b2b8b4bcb9fbb6bab8">[email protected]</a>");
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);
Method 2
First, you don’t need to manually read the values in your .config file. You can set the in the System.Net section and your SmtpClient object will read them automatically:
<system.net>
<mailSettings>
<smtp from="Sender's display name <<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="becddbd0dadbcce1dbd3dfd7d2fedad1d3dfd7d090ddd1d3">[email protected]</a>>">
<network host="mailserver.yourdomain.com" port="25" userName="smtp_server_username" password="secret" defaultCredentials="false" />
</smtp>
</mailSettings>
</system.net>
Then, from your code, you just write:
SmtpClient smtp = new SmtpClient();
MailMessage mailMessage = new MailMessage();
mailMessage.To.Add(new MailAddress("<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="b9cbdcdad0c9d0dcd7cdf9cad6d4dcddd6d4d8d0d797dad6d4">[email protected]</a>", "Recipient Display Name"));
mailMessage.Subject = "Some Subject";
mailMessage.Body = "One gorgeous body";
smtp.Send(mailMessage);
Coming back to your error, it would appear you have some kind of a network problem.
Method 3
I suggest you the simplest way to send email on exception – using Elmah. Please follow this guide line for the solution:
https://www.stormconsultancy.co.uk/blog/development/tools-plugins/setup-email-alerts-from-elmah-when-exceptions-are-raised/
Method 4
try
{
MailMessage mail = new MailMessage();
//SmtpClient SmtpServer = new SmtpClient("smtp.google.com");
SmtpClient SmtpServer = new SmtpClient(sServer);
// SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com", 587);
mail.From = new MailAddress(sFromEmailId);
mail.To.Add(sToEmailId);
mail.Subject = sSubject;
mail.Body = sMessage;
mail.IsBodyHtml = true;
HttpFileCollection hfc = Request.Files;
for (int i = 0; i < hfc.Count; i++)
{
HttpPostedFile hpf = hfc[i];
if (hpf.ContentLength > 0)
{
mail.Attachments.Add(new Attachment(fupload.PostedFile.InputStream, hpf.FileName));
}
}
SmtpServer.Port = 587;
//SmtpServer.Host = "smtp.gmail.com";
SmtpServer.DeliveryMethod = SmtpDeliveryMethod.Network;
SmtpServer.UseDefaultCredentials = false;
SmtpServer.Credentials = new System.Net.NetworkCredential(sFromEmailId, sPassword);
SmtpServer.EnableSsl = true;
SmtpServer.Send(mail);
ClientScript.RegisterStartupScript(this.GetType(), "Alert", "dim('Mail Sent Successfully..!');", true);
mail.Dispose();
}
catch (Exception ex)
{
ClientScript.RegisterStartupScript(this.GetType(), "Alert", "dim('Error in Sending Mail..!');", true);
}
Method 5
Another reason for this exception could be the anti virus installed on your system. This may be prohibiting the application to send mails. Just look out for a dialog box that is asking for permission to send mails through an application on your system.
