Error When Sending Email Using c#

[India777]

Hai all,
I got the Following Error When Sending Email to Live Address using SMTP in c#.

Error Details:

System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 192.168.7.90:25 at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.Sockets.Socket.InternalConnect(EndPoint remoteEP) at System.Net.ServicePoint.ConnectSocketInternal(Bool ean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Int32 timeout, Exception& exception) --- End of inner exception stack trace --- at System.Net.ServicePoint.GetConnection(PooledStream PooledStream, Object owner, Boolean async, IPAddress& address, Socket& abortSocket, Socket& abortSocket6, Int32 timeout) at System.Net.PooledStream.Activate(Object owningObject, Boolean async, Int32 timeout, GeneralAsyncDelegate asyncCallback) at System.Net.PooledStream.Activate(Object owningObject, GeneralAsyncDelegate asyncCallback) at System.Net.ConnectionPool.GetConnection(Object owningObject, GeneralAsyncDelegate asyncCallback, Int32 creationTimeout) at System.Net.Mail.SmtpConnection.GetConnection(Strin g host, Int32 port) at System.Net.Mail.SmtpTransport.GetConnection(String host, Int32 port) at System.Net.Mail.SmtpClient.GetConnection() at System.Net.Mail.SmtpClient.Send(MailMessage message)

I use the Following Code For Sending

public string TestMail(string path)
{
    string sendto = "xxxx,xxxx,xxxx"
    string sendfrom = "xxxx";    
    string content = "Test Mail";
    string subject = "Mail from MyDomain.com";    
    string Email_Content ="This is test.Please Ignore it."
    string MailServerName = "xxxx";            
    string[] ToAddress = null;
    int i = 0;           
    ToAddress = sendto.Split(',');    
    try
    {
        SmtpClient mailSMTPClient = new SmtpClient("xxxx");
        mailSMTPClient.Credentials = new System.Net.NetworkCredential("xxxx","xxxx");
        MailAddress mailFromAddress = new MailAddress(sendfrom);               
        mailSMTPClient.UseDefaultCredentials = true;
        MailMessage mailMessage = new MailMessage();
        mailMessage.From = new MailAddress(mailFromAddress.ToString());
        for (i = 0; i <= ToAddress.Length - 1; i++)
        {
            mailMessage.To.Add(ToAddress[i].Trim());
        }
        mailMessage.To.Add(sendfrom.Trim());
 
        mailSMTPClient.EnableSsl = true;
        Attachment attachment = new Attachment(path);
        mailMessage.Attachments.Add(attachment);
        mailMessage.Subject = subject;
        mailMessage.Body = Email_Content;
        mailMessage.IsBodyHtml = true;
        var _with1 = mailSMTPClient;
        _with1.DeliveryMethod = SmtpDeliveryMethod.Network;
 
        _with1.Send(mailMessage);               
        return "Success";
 
    }
    catch (SmtpException ex1)
    {               
        string str = null;
        if (ex1.InnerException != null)
        {
            str = ex1.InnerException.ToString();
        }
        else
        {
            str = ex1.ToString();
        }        
        return str;
    }
}
