c# - 发送电子邮件的代码

Question

我在这里做错了什么？

 private void SendMail(string from, string body)
    {
        string mailServerName = "plus.pop.mail.yahoo.com";
        MailMessage message = new MailMessage(from, "aditya15417@yahoo.com", "feedback", body);
        SmtpClient mailClient = new SmtpClient();
        mailClient.Host = mailServerName;
        mailClient.Send(message);
        message.Dispose();
    }

我收到以下错误:

连接尝试失败，因为连接方在一段时间后没有正确响应，或者建立连接失败，因为连接的主机未能响应 209.191.108.191:25

您正在使用 wrong server .您将需要使用 SMTP 设置。

试试这个服务器:plus.smtp.mail.yahoo.com 他们的网站将这个主机标记为 SSL。

private void SendMail(string from, string body) 
{ 
    string mailServerName = "plus.smtp.mail.yahoo.com"; 
    int mailServerPort = 465;
    string toAddress = "aditya15417@yahoo.com";
    string subject = "feedback";

    string username = "user";
    string password = "password";

    SmtpClient mailClient = new SmtpClient(mailServerName, 
                                           mailServerPort); 
    mailClient.Host = mailServerName; 
    mailClient.Credentials = new NetworkCredential(username, 
                                                   password);
    mailClient.EnableSsl = true;

    using (MailMessage message = new MailMessage(from, 
                                                 toAddress, 
                                                 subject, 
                                                 body))
        mailClient.Send(message); 
}
