Hi friends,
I have problem while sending a mail using asp.net C#. got an error like failure sending mail.

i was tried port numbers of 25 and 587 both.
This is my code

C#

public bool sendMail(string mailID, string srvMailID, string srvMailPassword, string dispName, string mailSubject, string smtpHost, string mailDescription, string port)
    {
        bool sent = false;

        try
        {
            string frmAddress = srvMailID.ToString();
            string toAddress = mailID.ToString();


            System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();

            mail.To.Add(toAddress);

            mail.From = new System.Net.Mail.MailAddress(srvMailID, dispName.ToString(), System.Text.Encoding.UTF8);
            mail.Subject = mailSubject.ToString();
            mail.SubjectEncoding = System.Text.Encoding.UTF8;
            mail.Body = mailDescription.ToString();
            mail.BodyEncoding = System.Text.Encoding.UTF8;
            mail.IsBodyHtml = true;
            mail.Priority = System.Net.Mail.MailPriority.High;

            System.Net.Mail.SmtpClient Client = new System.Net.Mail.SmtpClient();

            Client.Credentials = new System.Net.NetworkCredential(frmAddress.ToString(), srvMailPassword.ToString());
            Client.Port = Convert.ToInt32(port);
            Client.Host = smtpHost.ToString();
            Client.EnableSsl = true;

            Client.Send(mail);
            sent = true;

        }
        catch (Exception ex)
        {
            sent = false;
        }
        finally
        {

        }
        return sent;
    }

the function calling is

C#

sendMail(Emaild, "softwarebuddy@gmail.com", "mypassword", "Rushi Tammisetti", "Password Recovery", "smtp.gmail.com", "Dear User Your Username Is is:" + username.ToString() + "\n Password is :" + pwd.ToString() + "", "587");

What's the exact error?

Rushi Raghava 20-Aug-13 22:37pm

failure sending mail(Exception)

Rushi Raghava 20-Aug-13 22:42pm

The inner exception was "unable to connect remote server"

There's your answer. You need to get with your SMTP admin and figure out what credentials and port you need.

I tested your code in a console application using port 25 and it sends the mail without getting any errors?
The layout of how you construct the message is not exactly how I would do it but it still works.
I have to note that the only thing I left out from your code is all the .ToString()s that you use, since you already declare it as a string.

Gmail works on Port 587 and it is tested at my end.

Follow my previous answer - sending email to gmail from asp.net[^].

If you still face the issue, then please check the InnerException to find the exact issue.
