Error sending mail through Yahoo?


Error sending email from yahoo. I have tried ports 25,995,465,587! I am out of options now. I would highly appreciate if someone could tell me what the problem is? isn't smtp available on yahoo now!!! i read somewhere that it is a paid service or something? is that correct and is it because of that, that i am not able to get through the server! I can successfully send emails from my gmail account where the To and From are same and i also sent a mail from gmail to Yahoo but the reverse isnt working!

 MailMessage mail = new MailMessage();
 mail.From = new MailAddress([email protected]);
 //***Enter recievers Email here (TVC)
 mail.To.Add(new MailAddress("[email protected]"));
 mail.Subject = "This is some text";
 mail.Body = "This is the body";
 SmtpClient client = new SmtpClient("plus.smtp.mail.yahoo.com",995);
 client.Credentials = new System.Net.NetworkCredential("[email protected]", "pass");
 client.EnableSsl = true;
 client.Send(mail);
 MessageBox.Show("Mail Sent Successfully!", "Success", MessageBoxButtons.OK);

I get the following exception

System.Net.Mail.SmtpException was unhandled
Message=Failure sending mail.

Solution

  • I don't think you can do that unless you are a Yahoo! Plus account holder.

    Read this: http://help.yahoo.com/l/us/yahoo/mail/classic/mailplus/pop/pop-08.html

    This is the link: Time out Error in send mail
    ( OP never believed it any way and so it was not marked as answer. Please note that the other answer is also unmarked which means OP did not get a solution )

    P.S: I have just checked sending a mail through "smtp.yahoo.com" port 465. Its also being forcibly closed. So as of now, its also not working.

    Hope this helps.
