Solution 1

Check the following points:

1- Check that this port 587 is open on your machine

2- Check if your antivirus is blocking the connection to your port

thx!

I check it out...
Firewall and antivirus both are disabled....

and how to check 587 open or not....?

Well you need to contact your ISP to make sure that port 587 is not blocked at his end. I faced same issue when i was configuring my gmail in outlook. i read this somewhere on internet and asked mi ISP to unblock the port and bingo it worked.

Hi,

Read the message in the above exception.

Message="Unable to connect to the remote server"

Message="No connection could be made because the target machine actively refused it 173.194.79.109:587"

It can be either due to the following reasons

Either u may be accessing the gmail from a pc to which the gmail connection may have been terminated ie either firewall may be blocking your access to gmail. Or connection may have been timed out.

Check it out.

yes connection has been timed out when it is running...

this error also comes when i testing this program ....

"The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.0 Must issue a STARTTLS command first. sf4sm5136790pbc.75"

Hi,
Look at the exception message, it clearly says "No connection could be made because the target machine actively refused it 173.194.79.109:587". So try enabling inbound and outbound rules for port 587 on the server.
You can find help from this article.

C#

var smtp = new System.Net.Mail.SmtpClient();
   {
       smtp.Host = "smtp.gmail.com";
       smtp.Port = 587;
       smtp.EnableSsl = true;
       smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
       smtp.Credentials = new NetworkCredential(fromAddress, fromPassword);
       smtp.Timeout = 20000;
   }
   // Passing values to smtp object
   smtp.Send(fromAddress, toAddress, subject, body);

Hi Niravvasoya,

Try this piece of code

C#

 System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
 message.To.Add("yourid@provider.com");
 message.Subject = "Trial Mail";
 message.From = new System.Net.Mail.MailAddress("myid@provider.com");
 message.Body = "Hi this is a trial mail"
 message.IsBodyHtml = true;

 System.Net.Mail.SmtpClient smtp = new                                  System.Net.Mail.SmtpClient("mail.provider.com"); //in case of gmail give as smtp.gmail.com
try
{
    smtp.EnableSsl = false;//try notching with true or false.
    smtp.UseDefaultCredentials = false;//try notching with true or false
    //smtp.Port = 25;
    smtp.Port = 587;//for gmail port is 25.
    System.Net.NetworkCredential NetworkCred = new System.Net.NetworkCredential();
    NetworkCred.UserName = "myid@provider.com";
    NetworkCred.Password = "*****";
    smtp.Credentials = NetworkCred;
    smtp.Send(message);

}
catch (Exception ex)
{
    message.Dispose();
    smtp = null;

}

This works out fine for me.

Hope this works for u too..

Good luck.
