I am trying to send an email from a computer outside the company network using the company email server that has internet access though mail.mycompany.com - I keep getting host did not connect
here is the error
System.Net.Mail.SmtpException: Failure sending mail. ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 192.0.0.0



private void btnEmail_Click(object sender, EventArgs e)
        {
            if (txtbxEmail.Text.Trim() == string.Empty || txtbxName.Text.Trim() == string.Empty)
            {
                MessageBox.Show("You must enter a name and email address");
                return;
            }
            //create the mail message
            MailMessage mail = new MailMessage();

            //set the addresses
            mail.From = new MailAddress(txtbxEmail.Text);
            mail.To.Add("me@mycompany.com");
            //mail.ReplyTo(txtbxEmail.Text);

            //set the content
            mail.Subject = lblNotifier.Text;
            mail.Body = txtbxNumber.Text + " " + txtbxName.Text;
            

            //send the message
            //SmtpClient smtp = new SmtpClient            SmtpClient smtp = new SmtpClient("mail.mycompany.com");
            //smtp.Credentials = new System.Net.NetworkCredential(@"domain\me", "pass");
            smtp.
            //MessageBox.Show(smtp.ToString());
            smtp.Send(mail);
            btnEmail.Enabled = false;
            
            MessageBox.Show("Email Sent");
            this.Close();
            this.Dispose();

            

        }

Can you telnet on port 80 to the remote server?  From a different machine to the remote system, type telnet x.x.x.x 80 (replace x.x.x.x) with the actual ip address.  could be a windows firewall issue.
