Hi all
I am having trouble with sending email via a C#2.0 application, I use
the same settings as I use in Outlook but I cannot get email to send.
I am trying to use SSL on port 465 and get the error below, If I disable
SSL and use port 587 all goes well.
I have been Googling for 2 days without success and this seems to be a
common problem.
Any help is appreciated.
Thanks.
Here is the code I am using.
MailMessage message = new MailMessage();
message.From = new MailAddress("(e-mail address removed)");
message.Sender = new MailAddress("(e-mail address removed)");
message.To.Add(new MailAddress("(e-mail address removed)"));
message.Subject = "This is my subject";
message.Body = "This is the content";
SmtpClient smtpClient = new SmtpClient("smtp.bizmail.yahoo.com", 465);
System.Net.NetworkCredential mc = new
System.Net.NetworkCredential("(e-mail address removed)", "mypassword");
smtpClient.UseDefaultCredentials = false;
smtpClient.Credentials = mc ;
smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network ;
smtpClient.EnableSsl = true;
try{
smtpClient.Send(message);
}
catch(Exception e) {
System.Console.WriteLine(e.InnerException.ToString());
}
smtpClient = null;
Console.Write("Press any key to continue . . . ");
Console.ReadKey(true);
The error I get is this:
Unable to read data from the transport connection: An existing
connection was forcibly closed by the remote host.
